4509 5549 d 3 h decky /trunk/uspace/ rename libadt -> adt  
4463 5553 d 22 h decky /trunk/uspace/srv/vfs/ VFS rewrite:
- add new VFS methods
- VFS_NODE for getting VFS node for a file descriptor
- VFS_OPEN_NODE for opening an i-node directly
- VFS_DEVICE for getting the underlying device of a file (if any)
- VFS_SYNC for syncing buffers
- L_OPEN flag is set to underlying filesystem in VFS_LOOKUP when opening a file to support initialization (if any)
- VFS_CLOSE is now propagated to underlying filesystem to support cleanup (if any)		  
4401 5569 d 21 h svoboda /trunk/uspace/ C binding for devmap. Gets rid of duplicate code.  
4368 5579 d 8 h jermar /trunk/uspace/ Lookup a node's parent lexically rather than using the broken L_PARENT flag of
VFS_LOOKUP.		  
4305 5600 d 2 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 5647 d 0 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 5676 d 18 h jermar /trunk/uspace/srv/ Nuke VFS operations structure.  
3653 5740 d 1 h jermar /trunk/uspace/srv/vfs/ Hold the namespace_rwlock during readdir().  
3215 5885 d 4 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 5916 d 2 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 5919 d 2 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2821 5975 d 16 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2770 6002 d 21 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6004 d 21 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 6005 d 0 h jermar /trunk/uspace/ Support for rename().  
2752 6012 d 2 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2742 6017 d 19 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 6026 d 1 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6026 d 2 h jermar /trunk/uspace/ Support for close().  
2731 6026 d 4 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.
