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.
2957

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.
2769

VFS index needs to be treated as uint64_t.

Fibril serialization is required when two file systems register contemporarily.

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
6042 d 16 h
jermar
/trunk/uspace/
Support for rename().
2753

Move canonify() to libc so that it can be used also on the libc side.
2752
6049 d 18 h
jermar
/trunk/uspace/srv/vfs/
Make VFS canonify path names on lookup.
2751
6050 d 16 h
jermar
/trunk/uspace/
Add canonify() for file system path canonization.
Not yet used by VFS.

contents_rwlock should not be acquired as a futex but rather as a rwlock.
2748
6052 d 12 h
jermar
/trunk/uspace/srv/vfs/
Support for O_TRUNC.
2742
6055 d 11 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().
2740
6061 d 11 h
jermar
/trunk/uspace/srv/vfs/
Initialize the VFS node properly.
2735
6063 d 17 h
jermar
/trunk/uspace/
Support for rmdir(), unlink() and the respective VFS operations.
2734
6063 d 19 h
jermar
/trunk/uspace/
Support for close().
2731
6063 d 20 h
jermar
/trunk/uspace/srv/
Add the VFS_FREE operation. This operation frees up whatever resources used by
a file system node for which there is no name (i.e. an unlinked node).
Cleanup VFS operations enums and remove unneeded VFS operations.
2730
6064 d 22 h
jermar
/trunk/uspace/srv/
Introduce the notion of VFS node link counts.
2710

VFS_WRITE and tmpfs_write fixes.
2709
6084 d 17 h
jermar
/trunk/uspace/srv/vfs/
VFS_OPEN and VFS_WRITE now understand O_APPEND.
2708
6084 d 17 h
jermar
/trunk/uspace/
VFS_OPEN now understands O_CREAT and O_EXCL.
2707
6084 d 19 h
jermar

Support for mkdir().
2704
6085 d 21 h
jermar
/trunk/uspace/srv/vfs/
Additional VFS lookup flags.
2700
6092 d 20 h
jermar
/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).
2698

jermar
/trunk/uspace/srv/vfs/
Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
2693
6098 d 20 h
jermar
/trunk/uspace/
Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
2691
6102 d 14 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().
2690
6103 d 12 h
jermar
/trunk/uspace/srv/
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.
2689
6103 d 13 h
jermar
/trunk/uspace/srv/vfs/
Merge all VFS operations into one file.
