-Subject: scsi: megaraid_sas: Fix data integrity failure for JBOD (passthrough) devices
-
-From: Kashyap Desai <kashyap.desai@broadcom.com>
-
-commit 1e793f6fc0db920400574211c48f9157a37e3945 upstream.
-
-Commit 02b01e010afe ("megaraid_sas: return sync cache call with
-success") modified the driver to successfully complete SYNCHRONIZE_CACHE
-commands without passing them to the controller. Disk drive caches are
-only explicitly managed by controller firmware when operating in RAID
-mode. So this commit effectively disabled writeback cache flushing for
-any drives used in JBOD mode, leading to data integrity failures.
-
-[mkp: clarified patch description]

-Fixes: 02b01e010afeeb49328d35650d70721d2ca3fd59
