Miklos Szeredi a105d685a8 ovl: fix remove/copy-up race ... ovl_remove_and_whiteout() needs to check if upper dentry exists or not after having locked upper parent directory. Previously we used a "type" value computed before locking the upper parent directory, which is susceptible to racing with copy-up. There's a similar check in ovl_check_empty_and_clear(). This one is not actually racy, since copy-up doesn't change the "emptyness" property of a directory. Add a comment to this effect, and check the existence of upper dentry locally to make the code cleaner. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>		2014-11-20 16:39:59 +01:00
