Subject: [PATCH 08/24] nilfs2: introduce GC subsystem debugging output option
Date: Mon, 17 Jun 2013 16:23:44 +0400 [thread overview]
Message-ID: <1371471824.2075.138.camel@slavad-ubuntu> (raw)
From: Vyacheslav Dubeyko <slava-yeENwD64cLxBDgjK7y7TUQ@public.gmane.org>
Subject: [PATCH 08/24] nilfs2: introduce GC subsystem debugging output option
This patch adds subsystem's flags for gcinode.c module.
Flags for these modules are grouped by CONFIG_NILFS2_DEBUG_GC_SUBSYSTEM
kernel configuration option. This kernel configuration option enables
(or disables) debugging output from of all above-mentioned modules.
