Jaegeuk Kim 22ad0b6ab4 f2fs: add bitmaps for empty or full NAT blocks ... This patches adds bitmaps to represent empty or full NAT blocks containing free nid entries. If we can find valid crc|cp_ver in the last block of checkpoint pack, we'll use these bitmaps when building free nids. In order to avoid checkpointing burden, up-to-date bitmaps will be flushed only during umount time. So, normally we can get this gain, but when power-cut happens, we rely on fsck.f2fs which recovers this bitmap again. After this patch, we build free nids from nid #0 at mount time to make more full NAT blocks, but in runtime, we check empty NAT blocks to load free nids without loading any NAT pages from disk.
