  nilfs2: shorten freeze period due to GC in write operation v3
  nilfs2: add more check routines in mount process
  nilfs2: An unassigned variable is assigned to a never used structure member
  nilfs2: use GFP_NOIO for bio_alloc instead of GFP_NOWAIT
  nilfs2: stop using periodic write_super callback
  nilfs2: clean up nilfs_write_super
  nilfs2: fix disorder of nilfs_write_super in nilfs_sync_fs
  nilfs2: remove redundant super block commit
