Revision 722d90822321497e2837cfc9000202e256e6b32f authored by Mike Snitzer on 14 June 2023, 00:05:34 UTC, committed by Mike Snitzer on 15 June 2023, 16:46:59 UTC
issue_discard() passes GFP_NOWAIT to __blkdev_issue_discard() despite
its code assuming bio_alloc() always succeeds.
Commit 3dba53a958a75 ("dm thin: use __blkdev_issue_discard for async
discard support") clearly shows where things went bad:
Before commit 3dba53a958a75, dm-thin.c's open-coded
__blkdev_issue_discard_async() properly handled using GFP_NOWAIT.
Unfortunately __blkdev_issue_discard() doesn't and it was missed
during review.
