3478 5934 d 11 h decky /branches/arm/ new arm branch  
3109 6047 d 7 h jermar /trunk/uspace/srv/ Split the 'mount another filesystem here' and 'you are being mounted and the
device is this' mount semantics. Add VFS_MOUNTED VFS operation that corresponds
to the latter and reserve VFS_MOUNT only for the former. Because of this
change, the VFS server does not maintain the mr_node VFS node for the name space
root anymore and the VFS_LOOKUP operation is now not meant to be used on
unmounted file system, not even for looking up the root node of unmounted file
systems. In the light of these changes, TMPFS is now initialized from
tmpfs_mounted() function.		  
2770 6134 d 2 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 6135 d 0 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2766 6136 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 6136 d 5 h jermar /trunk/uspace/ Support for rename().  
2753 6143 d 1 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 6143 d 7 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6144 d 5 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2730 6158 d 11 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2707 6178 d 7 h jermar /trunk/uspace/ Support for mkdir().  
2700 6186 d 9 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 6187 d 4 h jermar /trunk/uspace/srv/vfs/ Small fix for VFS_TRUNCATE. Move lookup and registration code to separate
modules.
