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.

/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().

Initialize the VFS node properly.

/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.

6157 d 8 h

/trunk/uspace/srv/
Introduce the notion of VFS node link counts.

/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().

Management of the cached VFS node size.

/trunk/uspace/
Add basic rwlock API for uspace so that VFS can be designed/implemented using
this API. So far, the implementation of this API merely wraps futexes into
rwlocks. Real rwlocks are wanted by ticket #54.
Using the new rwlock API, replace the VFS node content futex with an rwlock.
Lock the contents rwlock as reader on reads and as writer on writes.

Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.

VFS work.
Fix VFS node hash function to hash only within the limits of its supposed
ranges.

VFS work.
Implement VFS node hash table management.

6260 d 23 h
jermar
/trunk/uspace/srv/vfs/
A lot of more VFS prototyping.
VFS_OPEN gets reasonably complete, fix a limitation that prevented file
structures from being shared by multiple file descriptors, add functions for
file descriptor management, introduce unlink_futex and two new VFS operations
VFS_UNLINK and VFS_RENAME.

/trunk/uspace/srv/vfs/
VFS work.
Start implementing VFS side of VFS_OPEN.
Add vfs_node.c to contain VFS node related internal functions.
