[PATCHES 0/3] Mem accounting and IRQ req cache

[Jens Axboe <axboe@xxxxxxxxx>]

Hi,

This builds on the stuff that Pavel and I have been tossing around:

Patch 1: Enable req cache for the last class of requests, those that end
	 up completing from IRQ context. That's regular file/bdev reads
	 and writes.

Patch 2: Enable SLAB_ACCOUNT/memcg accounting for requests

Patch 3: Use memcg for the ring array accounting as well. That moves it
	 outside of rlimit memlock, though we retain memlock accounting
	 for registered buffers.
