fd_and_path_to_vnode() now accepts NULL as path argument.
Added some more debug output and comments.

Also fixed a minor bug in dec_vnode_ref_count(): the unusued vnode counter
was not decremented again when one vnode was removed.

actually fills a cpuid_info structure. Renamed cpuid() to get_current_cpuid().
Added syscall _user_get_cpuid().
Added a lot of other vendor brand strings. The cpu_type and cpu_revision
fields should now be correctly set.
get_cpuid() now returns B_BAD_VALUE if the cpuNum parameter is out of bounds
(ie. higher than the number of available CPUs in the system).

team_init() now returns a status_t.
System info stuff is now globally initialized in main().
get_system_info() now also reports the number of used pages, and calls the
architecture dependent function.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10315 a95241bf-73f2-0310-859d-f6bbb57e9c96
added get_cpuid() function (does not respect the cpu parameter yet).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10314 a95241bf-73f2-0310-859d-f6bbb57e9c96
and no longer relies on put_vnode() for the root node. This will also call
the FS release/remove vnode calls. Extended comments.
Added "flags" parameter to unmount.

(free_vnode()). Upon freeing, the file cache is now only written back if the
file is not deleted.
dec_vnode_ref_count() no longer frees vnodes that are not going to be deleted.
Instead, it will add them to an unused vnode list, so that they can be freed
if needed (currently only 512 unused vnodes will be kept around). This should
speed up the whole thing, and makes the file cache much more useful, as it's
no longer dumped after the file is closed.
fs_unmount() is not yet respecting this (ie. it doesn't free those nodes as
it should).

Ceccherini for the hint.
The first port ID is now 1 and not 0 anymore.
Added a first free slot hint to speed up port creation.
Added more debug output when tracing is enabled.

BeOS supports this as well, at least it's not documented in the BeBook
(but it's useful anyway).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10259 a95241bf-73f2-0310-859d-f6bbb57e9c96
Renamed _user_set_tzspecs() to _user_set_timezone().
Renamed sTzFilename to sTimezoneFilename.
Moved rtc_print() into rtc_debug().
Fixed changing system_time_offset; since this is a shared 64 bit value,
we have to use atomic calls when we change it.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10253 a95241bf-73f2-0310-859d-f6bbb57e9c96
and only the syscall is exported.
For now, it always returns B_ENTRY_NOT_FOUND - since the boot loader
does not have support for driver settings yet.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10237 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added _user_shutdown() and made it available as syscall.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10233 a95241bf-73f2-0310-859d-f6bbb57e9c96
Implemented F_DUPFD support for fcntl() - we no longer see any redirection errors when
booting into Haiku.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10221 a95241bf-73f2-0310-859d-f6bbb57e9c96
_user_create_area() and _user_clone_area() now inherit the read/write protection
for the kernel, too - before, it was always mapped read/write in the kernel,
but there is no reason to do that.

Implemented new function vm_cache_write_modified() which will write all
dirty pages of this cache back to disk (using the new vm_page_write_modified()
function).
Fixed warnings when compiled with debug output.

git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10204 a95241bf-73f2-0310-859d-f6bbb57e9c96
While we can tolerate the device driver to ignore the bytes argument when we
read from the device, we cannot do this for writes - now the code actually
takes this into account. Also added a comment about what to do when our own
driver is fixed :)
Implemented file_cache_sync().
file_cache_set_size() now uses vm_cache::virtual_size instead of the now
removed vnode_store::size. Also, it now resizes the vm_cache as well, so
that any no longer used pages are freed.
write_to_cache() now puts all pages in the modified list, so that they
can be written back easily.
Improved debug output.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10203 a95241bf-73f2-0310-859d-f6bbb57e9c96
vm_cache::virtual_size is now used by the file cache code.

dec_vnode_ref_count() now deletes the cache *after* calling the file system's
remove/release vnode function. Also, it will now write back any pending
changes in that cache before removing it.
Some cleanup.

As a quick hack, they no longer disable interrupts, so that the env memory

Fixed a bug in the team thread start: it did not set sizeLeft correctly
before copying the arguments - shouldn't have had any consequences, though,
as the size of the arguments is known before.
Added a comment explaining the current layout of the main thread stack area.
Now makes use of B_STACK_AREA and B_KERNEL_STACK_AREA.
fill_thread_info() did not correctly set thread_info::stack_end.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10016 a95241bf-73f2-0310-859d-f6bbb57e9c96
Fixed a bug in arch_init_tls() that did not support different stack sizes
(ie. didn't use the thread::user_stack_size variable).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10015 a95241bf-73f2-0310-859d-f6bbb57e9c96
B_BAD_HANDLER, vm_soft_fault() will just continue as if there is no fault()
function.
There is now support for the B_STACK_AREA and B_KERNEL_STACK_AREA protection
values: if the former is used, or the latter in combination with DEBUG_KERNEL_STACKS,
a number of guard pages is inserted at the bottom of the stack (depending on
the STACK_GROWS_DOWNWARDS/UPWARDS arch config).
In addition, user stacks are no longer committed completely, ie. they don't
reserve memory for their whole size, only as much as is needed. That may
result in applications crashing when they need a lot of stack and there is
no memory left. Before this change, you could not even run that application.
Since BeOS has a 16 MB stack for the main thread, you could only run about
2 applications with 64 MB before.
Due to these changes, we've now switched to the standard BeOS stack sizes.
Some minor cleanup.

- added user data pointer to cache_transaction notifier
- added functions block_cache_set_dirty(), and block_cache_make_writable()
- cache_transaction_next_block() let's you iterate over all blocks in the transaction
- instead of binding the block contents to the transaction (read-only checked
out blocks did only see the unchanged blocks until the transaction was closed)
the block now always shows the current data - even if the old way had some
advantages, it was terrible to use
- the blocks were not correctly added to the transaction
- improved debug output
- can check if the read-only blocks were changed accidently (compile time option)

Fixed the clone_area() command: B_CLONE_ADDRESS must not be used in the

Added an explanation on why the area is cloned at all.

Renamed vm_area::lock to vm_area::protection to be less confusing - wiring
is still called wiring, though (might be renamed to lock later, as that's
how BeOS calls it).
Renamed some global variables to match our naming scheme.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9860 a95241bf-73f2-0310-859d-f6bbb57e9c96

for temporary memory anymore, it's the store's responsibility to do that
correctly now, and that functionality is reached via the vm_cache using
vm_cache_set_minimal_commitment().
Therefore, the vm_store commit() function now returns a status instead of
the size that could be commited.
Replaced the max_commit mechanism with one that cares about the available
memory, stores can reserve and unreserve such memory. The anonymous_commit()
will now fail in case it could not reserve the needed amount of memory.

The inode now keeps track of the number of readers/writers.
Inode::BytesInChain() is now only used protected by the request lock.
Implemented some missing POSIX demands:
- when the last writer is closed, all waiting read requests are aborted
- pipefs_write() now returns EPIPE and signals the current thread with
SIGPIPE in case there are no readers left
- pipefs_read() will now return 0 in case there are no writers and no
unread buffers left in the pipe.

Changed the last argument of _kern_mount() to be a string rather than a void pointer.
Greatly reduced the stack usage of _user_mount(); it now uses KPath instead

devfs_read_link() and rootfs_read_link() could write beyond the buffer
size passed in (off by one).
The comment for _kern_read_link() didn't fit to what the function really
did.
common_read_link() no longer null terminates the link - it's the file
system's responsibility to do that.
fs_read_link() is not supposed to return the length of the link anymore,
but only B_OK for success.
Note, we deviate slightly from POSIX here, where even a buffer too small
would be filled, and no terminating null byte has to be written at all.
We always return an error in case the buffer is too small, and the link
is not partially copied into the buffer.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9652 a95241bf-73f2-0310-859d-f6bbb57e9c96
Made the FS internal API a bit more consistent.
Removed devfs_unlink(), and devfs_rename() (which was just returning EROFS
anyway) - the devfs now appears completely read-only to the user. All
changes are triggered by kernel internal APIs (most usually through either
the devfs itself (old style drivers), the disk_device_manager, or the
standard device_manager).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9645 a95241bf-73f2-0310-859d-f6bbb57e9c96
Also implemented the now needed devfs_read_link() function.

devfs_unpublish_partition() now also returns B_ERROR since it's not yet

Refactored the device publishing code, so that implementing devfs_publish_file_device()

* Added resolve_mount_point_to_volume_root() which does what
resolve_volume_root_to_mount_point() did. IOW the latter one didn't
do what it advertised.
* Fixed dir_vnode_to_path(). Basically broken due to the broken
resolve_volume_root_to_mount_point(), but also compared potentially
unrelated vnode IDs (belonging to different volumes).
* Fixed get_dir_path_and_leaf(). It didn't deal correctly with paths
ending in '/' (including the root dir).
* fs_mount() does now accept a NULL fsName, getting the FS name from
the DDM in this case.
* fs_mount() now also supports mounting file images; it lets the DDM
create a file device for them.

* fs_mount() and fs_unmount() are now aware of partitions. A device to
be mounted is looked up by the DDM and the mount state and mount
cookie of the corresponding KPartition are updated accordingly.
Still missing is support for mounting files. Moreover the device path
needs to be normalized.
* Added RecursiveLockAutoLocker class to ease the `goto errN' pain a bit.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9555 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made GetMediaStatus() a bit more robust. If the ioctl fails (e.g. if it
is not implemented as in Thomas' drivers), it gets the device geometry
and does not fail, if the device is not removable.
