3215 5793 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().		  
3201 5797 d 2 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5824 d 1 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 5827 d 1 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5842 d 18 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5842 d 19 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 5883 d 15 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5894 d 8 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 5910 d 19 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 5911 d 18 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 5911 d 20 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 5912 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 5912 d 23 h jermar /trunk/uspace/ Support for rename().  
2753 5919 d 18 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 5920 d 1 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 5920 d 23 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 5922 d 18 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 5922 d 18 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 5925 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().		  
2740 5931 d 18 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.
