4368 5558 d 7 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4305 5579 d 0 h jermar /trunk/uspace/ Support mount options.
Let tmpfs decide whether to start empty or restored a TMPFS dump based on the mount option.		  
4010 5625 d 22 h decky /trunk/uspace/srv/vfs/ support for pending (blocking) mounts (waiting for the presence of the filesystem implementation)
the mount point and filesystem type arguments of VFS_MOUNT were swapped, the IPC_M_PING was eliminated
small cleanups		  
3845 5655 d 16 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3653 5719 d 0 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3215 5864 d 3 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 5895 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 5898 d 1 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 5954 d 14 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 5981 d 19 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 5983 d 20 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 5983 d 22 h jermar /trunk/uspace/ Support for rename().  
2752 5991 d 1 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 5996 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 6004 d 23 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6005 d 1 h jermar /trunk/uspace/ Support for close().  
2731 6005 d 2 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 6006 d 4 h jermar /trunk/uspace/srv/ Introduce the notion of VFS node link counts.  
2709 6025 d 23 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.  
2707 6026 d 1 h jermar /trunk/uspace/ Support for mkdir().
