generates the jobs needed to transform the former to the state of the
latter. Currently only the jobs for deleting partitions and resizing
and moving existing ones are generated. Resizing and moving was the
hard part, though, the rest should be much easier. Completely untested
yet.

now no longer set in the loop, the total_length calculation should now be correct.
The CBUF_FLAG_CHAIN_TAIL is now set for the lastBuffer instead of buffer.
Removed some superfluous lines in cbuf_get_ptr(), and cbuf_ones_cksum16().
Fixed the buffer->length calculation in cbuf_truncate_tail() and added some
comments about the correctness of the code - should be investigated and fixed.

to the module interfaces. So the disk system will be informed, when a
shadow partition has changed and it is allowed to do necessary
adjustions (e.g. adjusting the cookie, the parameters, or on
partitioning system initialization even creating special child
partitions (apple partitioning system)).
* Added `int32 *index' parameter to ValidateCreateChild(). So the
partitioning system can report at which index the new child shall be
inserted.

* Implemented _kern_resize_partition().

PrettyName() of the responsible disk system.
* Added change counter support and changes tracking.
* Added UninitializeContents().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4042 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed the disk_system_id parameter where superfluous.
* Got rid of the `child' variants of the _kern_{supports,validate}_*()
syscalls for moving and resizing. Reimplemented the real ones to do the
the right thing, i.e. they check all concerned disk systems now.
* Added _kern_supports_setting[_content]_parameters().
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4020 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed handling of the deletion (removal) of shadow partitions. Formerly
the shadow partition corresponding to the disk device wasn't removed
properly.
* Added a shadow_id field to the user_partition_data structure which
contains the ID of the shadow partition, if it is one. The id field
will hold the ID of the physical partition.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3974 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented the syscalls for iterating through and finding disk systems.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3902 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Writing disk device/partition data into userland buffer added.
* Migration of some definitions into <DiskDeviceDefs.h> header.
* Small bug fixes.

that exists on-disk, while KShadowPartition is a partition edited by the
API user, but not yet written to disk. Related changes in other classes.

is discarded right now (will use cbufs for this).
Pipes can now actually be created and removed - this didn't work before.
Changed some lock types to better suit their needs.
Small fixes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3708 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed cbuf_get_len() to cbuf_get_length().
Fixed a bug in cbuf_get_length() that would have returned an error code in
a size_t (now returns 0 in that case).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3692 a95241bf-73f2-0310-859d-f6bbb57e9c96

*not* change the previous behaviour (well, I added some debug output), since
the former recursive_lock_create() did always return B_OK, no matter if the
lock could be initialized or not.

recursive_lock_create()) - this reveals bugs in other parts of the system (VM),
but those won't be fixed for now (because of VM2).
Added the possibility of giving a recursive lock a name.
Moved the functions for benaphores and rw-locks to this file (they were
part of the lock.h header as defines).
Removed unused headers.
Small cleanup.

* Implemented delete_partition(). The device/partition management functions
should now be complete.

management regarding removal and deletion of objects.
* Fixed the file disk system related stuff. KFileDiskSystem now uses the
virtualdrive driver. The former method was seemed simple and brilliant,
but the B_SET_PARTITION ioctl wouldn't work.

KPartition and as no-ops in KDiskDevice.
* Prefixed partition names with "obos_" to not interfere with R5's
partition names.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3509 a95241bf-73f2-0310-859d-f6bbb57e9c96
Some changes to KPartition, KDiskDevice, KDiskSystem on this way.
Still missing is KPartition::Publish() and its invocation in
KDiskDeviceManager. Then everything should be in place to start with
porting the scanning parts of our disk system modules.

implementing a more efficient on_exit_thread().
Note, this extra parameter is currently only used for user space code,
not yet in the kernel; thus on_exit_thread() is not available in the kernel.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@3075 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added TRACE_SMP and a TRACE() macro that is used instead of dprintf() directly.
Also fixed all warnings with TRACE_SMP set to 1.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2941 a95241bf-73f2-0310-859d-f6bbb57e9c96

normally, I wouldn't checkin a file with cosmetic changes only
however, Marcus just made a change on this file earlier today,
so the file would have to be rebuilt anyway -- might as well
make it pretty too!

but doesn't have to be read from disk for efficiency reasons.
Fixed a bug in get_vnode() in case of fs->get_vnode() returns an error of some
kind.
fs_mount() no longer hides the return code from the fs->mount() function anymore (for now).
Added some comments and ToDo items.
Changed some return error values to the B_xxx style (will probably need to define
some new error codes for OpenBeOS).
Changed some return types to status_t/void where appropriate.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2786 a95241bf-73f2-0310-859d-f6bbb57e9c96
Changed apic_read()/apic_write() to accept offsets not addresses as register
parameter.
Cleanups.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2599 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a SIGNAL_TO_MASK() macro.
Removed the useless disable_interrupts() call in set_alarm().
More cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2584 a95241bf-73f2-0310-859d-f6bbb57e9c96

Now has user_*() functions where needed.
Moved thread_set_priority() from scheduler.c to set_thread_priority().
Renamed thread_wait_on_thread() to wait_for_thread().
user_get_thread_info() now uses user_strlcpy() instead of user_strncpy().
Fixed the snooze() implementation - it now returns B_OK where appropriate. Now all snooze()
calls will call snooze_etc().
New private call spawn_kernel_thread_etc() to replace thread_create_kernel_thread_etc().
Moved some functions around.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2578 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in sigaction(): it would have crashed with act/oact == NULL (which
is perfectly legal).
Now directly exports the kernel API.
Now has user_*() calls where needed.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2577 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed team_wait_on_team() to wait_for_team() (more BeOS-alike).
Adapted to other changes (new thread functions).
Cleanups.

Moved thread_set_priority() back to thread.c where it belongs to.

Removed stubs for send_notification() and notify_listener() (they are now located

Added support for the node monitoring service.

unmounts is not yet implemented.
Added an empty implementation for send_notification() - the function that is
(or will be) able to send out BMessages from within the kernel; currently
just prints out what should be done.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2481 a95241bf-73f2-0310-859d-f6bbb57e9c96

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2426 a95241bf-73f2-0310-859d-f6bbb57e9c96
arch_cpu: could have used the TLS_SIZE macro in one place, removed
a now unused variable, assignments to tss_loaded are now booleans.
thread.c: added the new fields to _dump_thread_info().

from the USER_STACK_REGION (until B_BASE_ADDRESS is available), made it much better
readable. It now grows from the lower USER_STACK_REGION up to the start of the main
thread's stack location.
Calls arch_thread_tls_init() and accounts for the TLS area in the stack region.
Added some comments, some cleanups.

area. It now also calls arch_thread_init_tls(). Cleaned it up to make it more
readable, added some comments.
Some other cleanups.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2381 a95241bf-73f2-0310-859d-f6bbb57e9c96
and TSS_BASE_SEGMENT in i386_set_tss_and_kstack() (thanks Daniel for pointing this
out)).
Added a arch_thread_init_tls() function which fills the reserved slots - the find_thread()
inline asm in OS.h is finally working.
Added some more comments, resolved the ToDo items from last time :-)
arch_thread_context_switch() now calls set_tls_context() at the correct location.
arch_thread_enter_uspace() now calls set_tls_context() as there is no context
switch in this case for the current thread after TLS has been set up, and it
now gets a pointer to the thread structure directly, and calculates the user
stack top itself, rather than the callee.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2380 a95241bf-73f2-0310-859d-f6bbb57e9c96
at all, and assumes a fixed and wrong number of preallocated GDT entries.
Implemented TLS: there is one GDT entry per CPU. If a context switch happens,
the FS register of the new thread is set to the matching GDT, and the GDT is
changed so that it points to the current thread's TLS storage area.
This area currently resides unsafely at the bottom of the user stack - for
some reason I could not figure out, it doesn't even work correctly most of
the time (it segfaults when accessing a slot via FS). I've added a ToDo item
explaining the situation - hopefully I have more ideas when I slept a bit more...
The GDT is now no longer static in arch_cpu.c and has been renamed from gdt to
gGDT. It's now also referenced in arch_thread.c, and it would make sense for
arch_selector.c to use it as well (instead of another local copy).
arch_cpu_init2() now uses the set_tss_descriptor() inline function and the
TSS_BASE_SEGMENT macro to set up the TSS section. It now also sets up the
TLS segment descriptors (as TSS, one entry per CPU).
Since I removed desc_table from the headers (the GDT is now a (segment_descriptor *)),
I added it locally to arch_int.c.
i386_enter_uspace() now don't set the FS register to 0x23 anymore, since it's
now already set correctly at the end of arch_thread_context_switch().
Some clean-ups.

I was too lazy to revert that little change back, so that I would be able
to write this short paragraph explaining what I've done.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2364 a95241bf-73f2-0310-859d-f6bbb57e9c96
some structure definitions (to outline some basic ideas), and the symbols
exported to userland.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2214 a95241bf-73f2-0310-859d-f6bbb57e9c96
Some int -> cpu_state cleanup on the way, and implement the
B_KDEBUG_CONT and B_KDEBUG_QUIT features in our kernel debugger.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2173 a95241bf-73f2-0310-859d-f6bbb57e9c96
code and made it much simpler (it now just uses a stack of path names
instead of this complex doubly-linked module_iterator_dir list).
Now works together with the rest of the code without making any problems.
Added a module_test() function which iterates over all existing modules.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2149 a95241bf-73f2-0310-859d-f6bbb57e9c96
Some cleanups, moved user_*() functions to the end of the file.

disabled. If a page fault happend while a interrupt handler is executed,
or while a section of code is running with interrupts disabled (with the
exception of the initial kernel startup), the page fault handler will
now panic, to give you the chance to fix the bug.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2124 a95241bf-73f2-0310-859d-f6bbb57e9c96
thread_exit() for now prints a warning if it was called with interrupts
disabled.
Fixed a bug in thread_exit2() that restored the interrupts too early,
instead of simply enabling them (and restoring them later) [found by
Marcus O. great debug additions].
Fixes for the khash changes.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2119 a95241bf-73f2-0310-859d-f6bbb57e9c96
Now the d_reclen field of struct dirent is correctly calculated in all
file systems (read_dir() function).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2114 a95241bf-73f2-0310-859d-f6bbb57e9c96
leak fixed, some other bugs fixed, removed the global queues as there weren't
needed and used at all, moved to the other hash table implementation
(because the new_hash_table stuff was buggy). Should really work okay now :-)
Added the last missing function get_next_loaded_module_name() - I am not
sure the Be version works this way, but we could easily change that after
actually having found out how that one is really working.
