From: Vyacheslav Dubeyko <slava@xxxxxxxxxxx> Subject: [PATCH 10/24] nilfs2: introduce recovery subsystem debugging output option This patch adds subsystem's flags for recovery.c module. Flags for these modules are grouped by CONFIG_NILFS2_DEBUG_RECOVERY_SUBSYSTEM kernel configuration option. This kernel configuration option enables (or disables) debugging output from of all above-mentioned modules.
