2788 5894 d 14 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5911 d 1 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5912 d 0 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5912 d 2 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5913 d 2 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 5913 d 4 h jermar /trunk/uspace/ Support for rename().  
2753 5920 d 0 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5920 d 6 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5921 d 5 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5923 d 0 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5923 d 0 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5925 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 5932 d 0 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.  
2735 5934 d 5 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5934 d 7 h jermar /trunk/uspace/ Support for close().  
2731 5934 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 5935 d 10 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2710 5955 d 3 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 5955 d 5 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2708 5955 d 5 h jermar /trunk/uspace/ VFS_OPEN now understands O_CREAT and O_EXCL.
