Subject: [PATCH V3 0/2] block/loop: improve performance
Date: Thu, 31 Aug 2017 22:09:44 -0700 [thread overview]
Message-ID: <cover.1504240556.git.shli@fb.com> (raw)
From: Shaohua Li <shli@fb.com>
two small patches to improve performance for loop in directio mode. The goal is
to increase IO size sending to underlayer disks.
Thanks,
Shaohua
V2 -> V3:
- Use GFP_NOIO pointed out by Ming
- Rebase to latest for-next branch
Shaohua Li (2):
block/loop: set hw_sectors
block/loop: allow request merge for directio mode
