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.
