Subject: [PATCH 01/27] target: remove an incorrect unmap zeroes data deduction
Date: Sat,  9 Apr 2022 06:50:17 +0200	[thread overview]
Message-ID: <20220409045043.23593-2-hch@lst.de> (raw)
In-Reply-To: <20220409045043.23593-1-hch@lst.de>

For block devices, the SCSI target drivers implements UNMAP as calls to
blkdev_issue_discard, which does not guarantee zeroing just because
Write Zeroes is supported.

Note that this does not affect the file backed path which uses
fallocate to punch holes.
