Subject: [ 11/41] vfs: fix return value from do_last()
Date: Fri, 16 Mar 2012 16:38:21 -0700 [thread overview]
Message-ID: <20120316233811.589196908@linuxfoundation.org> (raw)
In-Reply-To: <20120316233829.GA14022@kroah.com>
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miklos Szeredi <mszeredi@suse.cz>
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.
