3215 5893 d 9 h jermar /trunk/uspace/srv/vfs/ Instead of aborting or crashing, return EBADF when an invalid file descriptor
is passed to vfs_close().		  
3201 5897 d 8 h svoboda /trunk/uspace/ Do not disassemble needlessly.  
3109 5924 d 7 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 5927 d 7 h decky /trunk/uspace/srv/vfs/ disable extensive debugging output  
2958 5943 d 0 h jermar /trunk/uspace/srv/ Make VFS_MOUNT call even when mounting the root file system.  
2957 5943 d 1 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 5983 d 20 h jermar /trunk/uspace/srv/vfs/ Update comment.  
2788 5994 d 14 h jermar /trunk/uspace/ Return EBUSY if trying to mount something over an already mounted root FS.
(Contributed by Tim Post)		  
2770 6011 d 1 h jermar /trunk/uspace/ Introduce fs_handle_t, dev_handle_t and fs_index_t.  
2769 6012 d 0 h jermar /trunk/uspace/srv/vfs/ VFS index needs to be treated as uint64_t.  
2768 6012 d 2 h jermar /trunk/uspace/srv/vfs/ Fibril serialization is required when two file systems register contemporarily.  
2766 6013 d 2 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 6013 d 4 h jermar /trunk/uspace/ Support for rename().  
2753 6020 d 0 h jermar /trunk/uspace/ Move canonify() to libc so that it can be used also on the libc side.  
2752 6020 d 7 h jermar /trunk/uspace/srv/vfs/ Make VFS canonify path names on lookup.  
2751 6021 d 5 h jermar /trunk/uspace/ Add canonify() for file system path canonization.
Not yet used by VFS.		  
2749 6023 d 0 h jermar /trunk/uspace/srv/vfs/ contents_rwlock should not be acquired as a futex but rather as a rwlock.  
2748 6023 d 0 h jermar /trunk/uspace/srv/vfs/ Support for O_TRUNC.  
2742 6025 d 23 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 6032 d 0 h jermar /trunk/uspace/srv/vfs/ Initialize the VFS node properly.
