3.0-stable review patch. If anyone has any objections, please let me know.
------------------ From: Miklos Szeredi <[email protected]> commit 7f6c7e62fcc123e6bd9206da99a2163fe3facc31 upstream. complete_walk() returns either ECHILD or ESTALE. do_last() turns this into ECHILD unconditionally. If not in RCU mode, this error will reach userspace which is complete nonsense.
