From: Mike Snitzer <snitzer@redhat.com> To: axboe@kernel.dk Cc: ming.lei@redhat.com, hch@lst.de, dm-devel@redhat.com, linux-block@vger.kernel.org Subject: [PATCH v2 0/4] block/dm: use BIOSET_PERCPU_CACHE from bio_alloc_bioset Date: Wed, 23 Mar 2022 15:45:20 -0400 [thread overview] Message-ID: <20220323194524.5900-1-snitzer@kernel.org> (raw) Hi Jens, I ran with your suggestion and DM now sees a ~7% improvement in hipri bio polling with io_uring (using dm-linear on null_blk, IOPS went from 900K to 966K). Christoph, I tried to address your review of the previous set. Patch 1 and 2 can obviously be folded but I left them split out for review purposes. Feel free to see if these changes are meaningful for nvme's use. Happy for either you to take on iterating on these block changes further or you letting me know what changes you'd like made. Thanks, Mike v2: add REQ_ALLOC_CACHE and move use of bio_alloc_percpu_cache to bio_alloc_bioset Mike Snitzer (4): block: allow BIOSET_PERCPU_CACHE use from bio_alloc_clone block: allow BIOSET_PERCPU_CACHE use from bio_alloc_bioset dm: enable BIOSET_PERCPU_CACHE for dm_io bioset dm: conditionally enable BIOSET_PERCPU_CACHE for bio-based dm_io bioset block/bio.c | 67 +++++++++++++++++++++++++++++++---------------- block/blk.h | 7 ----- drivers/md/dm-table.c | 11 +++++--- drivers/md/dm.c | 10 +++---- drivers/md/dm.h | 4 +-- include/linux/bio.h | 9 +++++++ include/linux/blk_types.h | 4 ++- 7 files changed, 71 insertions(+), 41 deletions(-) -- 2.15.0
