From 7f6c7e62fcc123e6bd9206da99a2163fe3facc31 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Tue, 6 Mar 2012 13:56:34 +0100 Subject: [PATCH] vfs: fix return value from do_last() 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.
