The code to fix stalls during free spache cache IO wasn't using the correct root when waiting on the IO for inode caches. This is only a problem when the inode cache is enabled with mount -o inode_cache This fixes the inode cache writeout to preserve any error values and makes sure not to override the root when inode cache writeout is done.
