Hi all, I just noticed that 3659fb5ac29a5e6102bebe494ac789fd47fb78f4 ("nvme: fix multipath crash caused by flush request when blktrace is enabled") has not been backported into 5.4 stable kernels, leaving CVE-2022-50388 unfixed. I assume this has happened because it did not trivially apply. Is this assumption correct? In this case please see the patch I'll send as reply. If not, what is the reason?
