[RFCv2 0/3] enable pool shrinking in page unit

[Gioh Kim]

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.
