Revision eeeefd41843218c55a8782a6920f044d9bf6207a authored by Christoph Hellwig on 05 February 2017, 17:10:35 UTC, committed by Jens Axboe on 06 February 2017, 16:34:46 UTC
Write Same can return an error asynchronously if it turns out the
underlying SCSI device does not support Write Same, which makes a
proper fallback to other methods in __blkdev_issue_zeroout impossible.
Thus only issue a Write Same from blkdev_issue_zeroout an don't try it
at all from __blkdev_issue_zeroout as a non-invasive workaround.
