When doing this, we see usage changes as
(sec) (bytes)
0: 401408 <== cp start
1: 98603008
2: 262705152
3: 433491968 <== wmark reclaim triggerd.
4: 486502400
5: 507748352
6: 524189696 <== cp ends (and hit limits)
7: 501231616
8: 499511296
9: 477118464
10: 417980416 <== usage goes below watermark.
11: 417980416
.....
If we have dirty_ratio, this result will be some different.
(and flusher thread will work sooner...)
Thanks,
