6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Garry <john.g.garry@xxxxxxxxxx>
[ Upstream commit ea6787c695ab7595d851c3506f67c157f3b593c0 ]
We check in submit_bio_noacct() if flag REQ_ATOMIC is set for both read and
write operations, and then validate the atomic operation if set. Flag
REQ_ATOMIC can only be set for writes, so don't bother checking for reads.
Fixes: 9da3d1e912f3 ("block: Add core atomic write support")
