3478 5937 d 3 h decky /branches/arm/ new arm branch  
3352 5972 d 19 h jermar /trunk/uspace/srv/ Add reference to the mounted FS root.

This makes it possible to keep the FS root logically unlinked (i.e. lnkcnt == 0)
because it prevents VFS from attempting to destroy it during closedir().		  
3255 5986 d 5 h jermar /trunk/uspace/ Fix the VFS protocol so that the client can determine that VFS_MOUNT failed due
to a request to mount an unregistered file system.		  
3215 6019 d 1 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3109 6049 d 23 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 6052 d 23 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 6068 d 16 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 6068 d 18 h jermar /trunk/uspace/srv/vfs/ Cram VFS_MOUNT into one message. This creates a hidden demand for the sixth IPC
argument as there might be a desire to pass some options/flags in the future.		  
2788 6120 d 7 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 6136 d 18 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2766 6138 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 6138 d 21 h jermar /trunk/uspace/ Support for rename().  
2752 6145 d 23 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2749 6148 d 17 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6148 d 17 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 6151 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 6159 d 22 h jermar /trunk/uspace/ Support for rmdir(), unlink() and the respective VFS operations.  
2734 6160 d 0 h jermar /trunk/uspace/ Support for close().  
2710 6180 d 20 h jermar /trunk/uspace/ VFS_WRITE and tmpfs_write fixes.  
2709 6180 d 22 h jermar /trunk/uspace/srv/vfs/ VFS_OPEN and VFS_WRITE now understand O_APPEND.
