2687 5976 d 9 h jermar /trunk/uspace/srv/ Management of the cached VFS node size.  
2680 5978 d 17 h jermar /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.		  
2679 5982 d 10 h jermar /trunk/uspace/srv/vfs/ Rename unlink_futex to namespace_futex and introduce a new futex for serializing
concurrent access to a VFS node's contents by multiple clients.		  
2652 5996 d 13 h jermar /trunk/uspace/srv/vfs/ VFS work.
Fix VFS node hash function to hash only within the limits of its supposed
ranges.		  
2596 6039 d 13 h jermar /trunk/uspace/srv/vfs/ VFS work.
Implement VFS node hash table management.		  
2593 6041 d 10 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.		  
2590 6042 d 13 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start implementing VFS side of VFS_OPEN.
Add vfs_node.c to contain VFS node related internal functions.
