f2fs: fix out-of free segments
This patch also reverts d0db7703ac1 ("f2fs: do SSR in higher priority").
This patch fixes out of free segments caused by many small file creation by
1) mkfs -s 1 2G
2) mount
3) untar
- preoduce 60000 small files burstly
4) sync
- flush node pages
- flush imeta
Here, when we do f2fs_balance_fs, we missed # of imeta blocks, resulting in
skipping to check has_not_enough_free_secs.
Another test is done by
1) mkfs -s 12 2G
2) mount
3) untar
- preoduce 60000 small files burstly
4) sync
- flush node pages
- flush imeta
In this case, this patch also fixes wrong block allocation under large section
size.
