Subject: [PATCH 5/5] f2fs: show more debug info for per-temperature log
Date: Thu, 18 Jun 2020 14:36:25 +0800 [thread overview]
Message-ID: <20200618063625.110273-5-yuchao0@huawei.com> (raw)
In-Reply-To: <20200618063625.110273-1-yuchao0@huawei.com>
- Add to account and show per-log dirty_seg, full_seg and valid_blocks
in debugfs.
- reformat printed info.
TYPE segno secno zoneno dirty_seg full_seg valid_blk
- COLD data: 1523 1523 1523 1 0 399
- WARM data: 769 769 769 20 255 133098
- HOT data: 767 767 767 9 0 167
- Dir dnode: 22 22 22 3 0 70
- File dnode: 722 722 722 14 10 6505
- Indir nodes: 2 2 2 1 0 3
