From: Vyacheslav Dubeyko <slava@xxxxxxxxxxx> Subject: [PATCH 12/24] nilfs2: introduce block mapping subsystem debugging output option This patch adds subsystem's flags for alloc.c, bmap.c, btnode.c, btree.c, direct.c modules. Flags for these modules are grouped by CONFIG_NILFS2_DEBUG_BLOCK_MAPPING kernel configuration option. This kernel configuration option enables (or disables) debugging output from of all above-mentioned modules.
