Hello, Current shrinking is not page unit, block unit. But shrinker returns the pool size in page unit, so it is confused. And there is no way to control pool size and shrink pool directly. I have 3 patches: 1. Patch 1/3: make pool be shrinked by page unit This patch trys to shrink pool in page unit. 2. Patch 2/3: enable debugfs to shrink page directly This patch enables debugfs to specify shrink amount. 3. Patch 3/3: limit pool size This patch specifies pool size limit. This patchset is based on linux-next-20141023.
