Subject: [PATCH] fs: jffs2: fix error value sign
Date: Sun, 14 Nov 2010 20:08:39 +0000 [thread overview]
Message-ID: <1289765320-6071-1-git-send-email-segoon@openwall.com> (raw)
do_verify_xattr_datum(), do_load_xattr_datum(), load_xattr_datum()
and verify_xattr_ref() should return negative value on error.
Sometimes they return EIO that is positive. Change this to -EIO.
