Subject: [PATCH 00/32] AIO performance improvements/cleanups, v3
Date: Wed, 26 Dec 2012 17:59:37 -0800 [thread overview]
Message-ID: <1356573611-18590-1-git-send-email-koverstreet@google.com> (raw)
Last posting: http://article.gmane.org/gmane.linux.kernel.aio.general/3242
As before, changes should mostly be noted in the patch descriptions.
Some random bits:
* flush_dcache_page() patch is new
* Rewrote the aio_read_evt() stuff again
* Fixed a few comments
* Included some more patches, notably the batch completion stuff
My git repo has Jens' aio/dio patches on top of this stuff. As of the
latest version, I'm seeing a couple percent better throughput with the
ring buffer, and I think Jens was seeing a couple percent better with
his linked list approach - at this point I think the difference is
noise, we're both testing with fairly crappy drivers.
Patch series is on top of v3.7, git repo is at
http://evilpiepirate.org/git/linux-bcache.git aio-upstream
Kent Overstreet (27):
aio: Kill return value of aio_complete()
aio: kiocb_cancel()
aio: Move private stuff out of aio.h
aio: dprintk() -> pr_debug()
aio: do fget() after aio_get_req()
aio: Make aio_put_req() lockless
aio: Refcounting cleanup
wait: Add wait_event_hrtimeout()
aio: Make aio_read_evt() more efficient, convert to hrtimers
aio: Use flush_dcache_page()
aio: Use cancellation list lazily
aio: Change reqs_active to include unreaped completions
aio: Kill batch allocation
aio: Kill struct aio_ring_info
aio: Give shared kioctx fields their own cachelines
aio: reqs_active -> reqs_available
aio: percpu reqs_available
Generic dynamic per cpu refcounting
aio: Percpu ioctx refcount
aio: use xchg() instead of completion_lock
aio: Don't include aio.h in sched.h
aio: Kill ki_key
aio: Kill ki_retry
block, aio: Batch completion for bios/kiocbs
virtio-blk: Convert to batch completion
mtip32xx: Convert to batch completion
