[f2fs-dev] [PATCH v1 2/2] f2fs: introduce get_section_mtime

From: liuderong When segs_per_sec is larger than 1, section may contain free segments, mtime should be the mean value of each valid segments, so introduce get_section_mtime to exclude free segments in a section. Signed-off-by: liuderong --- fs/f2fs/f2fs.h| 2 ++ fs/f2fs/gc.c | 15 ++-
