Compaction has been using watermark checks when deciding whether it was
successful, and whether compaction is at all suitable. There are few problems
with these checks.
- __compact_finished() uses low watermark in a check that has to pass if
the direct compaction is to finish and allocation
Compaction has been using watermark checks when deciding whether it was
successful, and whether compaction is at all suitable. There are few problems
with these checks.
