Subject: [PATCH 0/2] block: loop: fix stacked loop and performance regression
Date: Tue, 5 May 2015 19:49:53 +0800 [thread overview]
Message-ID: <1430826595-5888-1-git-send-email-ming.lei@canonical.com> (raw)
Hi,
The 1st patch convers to per-device workqueue because loop devices
can be stacked.
The 2nd patch decreases max active works as 16, so that fedora 22's
boot performance regression can be fixed.
