2766 5926 d 1 h jermar /trunk/uspace/srv/vfs/ 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 5926 d 4 h jermar /trunk/uspace/ Support for rename().  
2753 5933 d 0 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5933 d 6 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5934 d 4 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5935 d 23 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5936 d 0 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5938 d 23 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 5944 d 23 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 5947 d 5 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5947 d 6 h jermar /trunk/uspace/ Support for close().  
2731 5947 d 8 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 5948 d 10 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5968 d 2 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5968 d 4 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5968 d 5 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5968 d 6 h jermar /trunk/uspace/ Support for mkdir().  
2704 5969 d 9 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5976 d 7 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 5977 d 3 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
