From: Vyacheslav Dubeyko <slava@xxxxxxxxxxx> Subject: [PATCH 06/24] nilfs2: introduce segments subsystem debugging output option This patch adds subsystem's flags for segbuf.c, segment.c modules. Flags for these modules are grouped by CONFIG_NILFS2_DEBUG_SEGMENTS_SUBSYSTEM kernel configuration option. This kernel configuration option enables (or disables) debugging output from of all above-mentioned modules.
