Subject: [PATCHSET v3 0/9] blk-mq-sched and sbitmap shallow depth
Date: Thu, 10 May 2018 10:24:18 -0600 [thread overview]
Message-ID: <1525969467-12476-1-git-send-email-axboe@kernel.dk> (raw)
Found another issue in sbitmap around our wake batch accounting.
See the last patch for details.
This series passes my testing. The sbitmap change was improved
by Omar, I swapped in his patch instead.
