Subject: [PATCH V2 0/3] block/loop: handle discard/zeroout error
Date: Wed,  6 Sep 2017 17:13:23 -0700	[thread overview]
Message-ID: <cover.1504742003.git.shli@fb.com> (raw)

From: Shaohua Li <shli@fb.com>

Fix some problems when setting up loop device with a block device as back file
and create/mount ext4 in the loop device.

BTW: blkdev_issue_zeroout retries if we immediately find the device doesn't
support zeroout, but it doesn't retry if submit_bio_wait returns -EOPNOTSUPP.
Is this correct behavior?

Thanks,
Shaohua
