3352 5772 d 21 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 5786 d 7 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 5819 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().		  
3201 5823 d 4 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5850 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 5853 d 2 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5868 d 19 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5868 d 21 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.		  
2821 5909 d 16 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5920 d 9 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5936 d 20 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5937 d 19 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5937 d 21 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5938 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 5939 d 0 h jermar /trunk/uspace/ Support for rename().  
2753 5945 d 19 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5946 d 2 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5947 d 0 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5948 d 19 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5948 d 19 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.
