respective setter/getter methods to the KPartition class.
If a partition is mounted, the field will contain the cookie the
FS's mount() hook passed back to the VFS. This way the FS has
access to its internal data structures. We need the cooperation
of the VFS to get the cookie.

affected function, and added a test call to vfs_get_module_name(); our
bootfs cannot handle the path depth/length required to be a useful module
host, so we still have our recursive search algorithm in place for now.

vnode_path_to_vnode() can now return the type of the file, changed the parameter

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4559 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added a comment about how to traverse the module path to find a given module -
could well be that we got that wrong (too loose, it will work perfectly, though,
just slower than it could be).

"sudden unmounts" (as far as that can work). This replaces the weak
find_mount() call used at several places in the fs index functions.
Fixed a bunch of warnings, mostly unused prototypes and variables.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4445 a95241bf-73f2-0310-859d-f6bbb57e9c96
renamed user_??? functions into the new _user_??? naming style.

Reordered the syscalls a bit (in functional groups), not completely, though.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4354 a95241bf-73f2-0310-859d-f6bbb57e9c96
The lock_memory()/unlock_memory() functions cannot be implemented right
now, as the NewOS VM doesn't support locking.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@4337 a95241bf-73f2-0310-859d-f6bbb57e9c96
Made the "name" argument const for create_area_etc() and vm_map_physical_memory().
Moved some common conversion code (BeOS to NewOS VM constants) to separate
functions to clean them up a bit.
create_area() now automatically sets LOCK_KERNEL if the area is to be created
in kernel space (as I would guess BeOS does, too).

delete_area() now only allows to delete areas you have created
yourself before from userland, again.
The kernel's delete_area() still allows everything, though.

delete. Added a comment how the security should be improved by adding another
restriction.
Also mentioned that it's probably a bad idea that vm_delete_region() will
not wait until the region has been freed, but just "mark" it as to be freed.

that will call the internal vm_*() calls. This will make it easier to just
drop in another VM.
Also (partially - Ingo was faster) introduced the new syscall naming scheme
_kern_ & _user_ prefixes to them into the system namespace, and no longer
clobber the application namespace.
Removed the now unused user_vm_create_anonymous_region() call.

to work at all: recurse_directory() always returned failure, no matter what opendir()
returned (one semicolon too much), create_module() allocated only 4 bytes for
the module - sizeof(module) referred to the variable, not the structure name...
(the unfortunate consequences of the naming scheme I otherwise like very much -
it "just" took me 3 hours to hunt both bugs down).
Added some TRACE() and ASSERT()s.
Added a new debugger command "modules".

most cases.
* On construction the `busy' and `descendant busy' flags are set.

hard part, though, the rest should be much easier. Completely untested

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.

PrettyName() of the responsible disk system.

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.

Pipes can now actually be created and removed - this didn't work before.

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

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.

* 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,

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

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

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

is perfectly legal).
Now directly exports the kernel API.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2577 a95241bf-73f2-0310-859d-f6bbb57e9c96
