3478 5948 d 4 h decky /branches/arm/ new arm branch  
3215 6030 d 2 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 6061 d 0 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.		  
3079 6064 d 0 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 6120 d 14 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 6147 d 18 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6149 d 19 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 6149 d 22 h jermar /trunk/uspace/ Support for rename().  
2752 6157 d 0 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 6162 d 17 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().		  
2735 6170 d 23 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6171 d 0 h jermar /trunk/uspace/ Support for close().  
2731 6171 d 1 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 6172 d 4 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 6191 d 22 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 6192 d 0 h jermar /trunk/uspace/ Support for mkdir().  
2704 6193 d 3 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6200 d 1 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).		  
2693 6206 d 2 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6209 d 19 h jermar /trunk/uspace/srv/vfs/ Improve the API for converting (VFS triplets, size) to VFS nodes by introducing
a new type for results of vfs_lookup_internal().
