Revision bef13315e990fd3d3fb4c39013aefd53f06c3657 authored by Christoph Hellwig on 13 January 2017, 22:18:16 UTC, committed by Jens Axboe on 13 January 2017, 22:18:16 UTC
Discard can return -EIO asynchronously if the alignment for the request
isn't suitable for the driver, which makes a proper fallback to other
methods in __blkdev_issue_zeroout impossible. Thus only issue a sync
discard from blkdev_issue_zeroout an don't try discard at all from
__blkdev_issue_zeroout as a non-invasive workaround.
One more reason why abusing discard for zeroing must die..
