3343 5973 d 3 h decky /branches/sparc/ add sparc branch  
3215 6016 d 7 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 6047 d 5 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 6050 d 5 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 6106 d 19 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 6133 d 23 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6136 d 0 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 3 h jermar /trunk/uspace/ Support for rename().  
2752 6143 d 5 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 6148 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().		  
2735 6157 d 4 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6157 d 5 h jermar /trunk/uspace/ Support for close().  
2731 6157 d 6 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 6158 d 9 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 6178 d 3 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 6178 d 5 h jermar /trunk/uspace/ Support for mkdir().  
2704 6179 d 8 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 6186 d 6 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 6192 d 7 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.  
2691 6196 d 0 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().
