From 5b3d5aeaa333850756f41350fed2fc95912b2a4f Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 17 Dec 2012 16:02:59 -0800 Subject: fat: ix mount option parsing parse_options() is supposed to return value < 0 on error however we returned 0 (success) in a lot of cases. This actually was not a problem in practice because match_token() used by parse_options() is clever and catches most of the problems for us.
