BZ: 1948690
Upstream Status: RHEL-only
Forward-port RHEL8 NVMe changes to RHEL9. These changes were rejected by
Christoph Hellwig (hch is one of upstream's 4 NVMe maintainers). The
other (3) upstream NVMe maintainers don't have a problem with these
changes, but Christoph is hostile toward any changes that make NVMe work
better with dm-multipath (because he wants everyone to use NVMe's native
multipathing, doesn't care that others have reasons why they want to use
dm-multipath).
So unfortunately we need to just keep carrying these changes in RHEL.
Can revisit getting these changes to land upstream in time for RHEL10,
but I don't care to engage upstream (specifically hch) on this topic at
this point in time.
Thankfully these NVMe changes are _not_ intrusive, have proven
stable/useful in RHEL8 and were easily forward-ported from RHEL8 to
RHEL9.
