2766 5900 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 5900 d 3 h jermar /trunk/uspace/ Support for rename().  
2753 5906 d 23 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5907 d 6 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5908 d 4 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5909 d 23 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5909 d 23 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5912 d 22 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 5918 d 23 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 5921 d 4 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5921 d 6 h jermar /trunk/uspace/ Support for close().  
2731 5921 d 7 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 5922 d 9 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5942 d 2 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5942 d 4 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5942 d 4 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.  
2707 5942 d 6 h jermar /trunk/uspace/ Support for mkdir().  
2704 5943 d 9 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5950 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 5951 d 3 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
