Hello, Current shrinking is not page unit, block unit. But shrinker returns the pools size with page unit. So it is confused. And there is no ways to shrink at any moment and any amount. I have 2 patches: 1. Patch 1/2: make pool be shrinked by page unit This patch trys to shrink pool in page unit. 2. Patch 2/2: enable debugfs to shrink pool directly This patch enable debugfs to specify shrink amount. Thanks for any feedback. This patchset is based on linux-next-20141023.
