Hold the namespace_rwlock during readdir().

Fix assorted warnings.

Add reference to the mounted FS root.
This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().

Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system.

Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().

Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.

Make VFS_MOUNT call even when mounting the root file system.

Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.

Return EBUSY if trying to mount something over an already mounted root FS.

Introduce fs_handle_t, dev_handle_t and fs_index_t.

Grab the nodes_futex when manipulating node link counts in rename() and
_unlink().
Fix VFS futex definitions and declarations by replacing atomic_t by futex_t.
2763

Support for rename().

Make VFS canonify path names on lookup.

contents_rwlock should not be acquired as a futex but rather as a rwlock.
2748

jermar
/trunk/uspace/srv/vfs/
Support for O_TRUNC.
2742
6046 d 7 h
jermar
/trunk/uspace/srv/
Separate creation of a TMPFS node and its linking in the file system name space.
Rename VFS_FREE to VFS_DESTROY and destroy_node() to unlink_node().
2735
6054 d 13 h
jermar
/trunk/uspace/
Support for rmdir(), unlink() and the respective VFS operations.
2734

Support for close().

VFS_WRITE and tmpfs_write fixes.
2709
6075 d 13 h

VFS_OPEN and VFS_WRITE now understand O_APPEND.

VFS_OPEN now understands O_CREAT and O_EXCL.

Support for mkdir().

6083 d 16 h

/trunk/uspace/
Introduce the notion of lflag (i.e. lookup flags) to support the ability to
limit the scope of VFS node types that can be opened by open() and opendir(). In
the future, lflag will also specify actions for VFS_LOOKUP handlers that will be
carried out in situations such as the VFS node is not found (e.g. implementation
of mkdir() and open() with O_CREAT in oflag).

Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
2693
6089 d 16 h
jermar
/trunk/uspace/
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
2691
6093 d 9 h
jermar
/trunk/uspace/srv/vfs/
Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().

Make a distinction between VFS operations that are common to VFS and FS
implementations, operations that are VFS only and operations that are FS
implementations only.

/trunk/uspace/srv/vfs/
Merge all VFS operations into one file.
