Before calling f2fs_freeze, all writers would be suspended and sync_fs would be completed. So no f2fs has to do something. Just background gc operation should be skipped due to generate dirty nodes and data until unfreeze. Signed-off-by: Changman Lee Signed-off-by: Jaegeuk Kim --- Reading git-diff-tree failed
