Subject: [PATCH 04/11] ocfs2: One check less in ocfs2_statfs()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 4 Jul 2015 16:28:50 +0200

Delete a check for the variable "status" by adjustment of two jump targets
according to the Linux coding style convention.
Separate the exception handling statements from the ordinary execution path.
