| Subject: f2fs: move dir data flush to write checkpoint process |
| |
| [ Upstream commit b61ac5b720146c619c7cdf17eff2551b934399e5 ] |
| |
| This patch move dir data flush to write checkpoint process, by |
| doing this, it may reduce some time for dir fsync. |
| |
| pre: |
| -f2fs_do_sync_file enter |
| -file_write_and_wait_range <- flush & wait |
| -write_checkpoint |
| -do_checkpoint <- wait all |
| -f2fs_do_sync_file exit |
| |
| now: |
| -f2fs_do_sync_file enter |
| -write_checkpoint |
| -block_operations <- flush dir & no wait |
| -do_checkpoint <- wait all |
| -f2fs_do_sync_file exit |
