3845 5593 d 16 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3653 5656 d 23 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3215 5802 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 5833 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 5836 d 0 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 5892 d 14 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 5919 d 18 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 5921 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 5921 d 22 h jermar /trunk/uspace/ Support for rename().  
2752 5929 d 0 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 5934 d 16 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 5942 d 22 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 5943 d 0 h jermar /trunk/uspace/ Support for close().  
2731 5943 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 5944 d 3 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 5963 d 22 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 5964 d 0 h jermar /trunk/uspace/ Support for mkdir().  
2704 5965 d 3 h jermar /trunk/uspace/srv/vfs/ Additional VFS lookup flags.  
2700 5972 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 5978 d 2 h jermar /trunk/uspace/ Add ftruncate() and support for VFS_TRUNCATE to VFS and TMPFS.
