Kent, stop those attacks.  Maybe your patches are just simply not
correct?  Sometimes that might be on the eye of the beholder when it
is about code structure, but in may cases they simply are objectively
broken.

In this case you very clearly misunderstood how the FUA bit works on
reads (and clearly documented that misunderstanding in the commit log).
You've had multiple people explain to you how it is wrong, and the
maintainer reject it for that reason.  What other amount of arguments
to you want?  If you need another one: FUA is not just use NVMe and
SCSI where it is supported on reads even if not in the way you think,
but also for all kinds of other protocols.  Even if we ended up thinking
REQ_FUA on reads is a good idea (and so far no one but you does) you'd
need to audit all these to check if the behavior is valid, and most
likely add a per-driver opt-in.  But so far you've not even tried to
make the use case for your feature.

You have a very clear pattern where you assume you're perfect, everyone
else is stupid and thus must be overridden.  Most people (including me
recently) have mostly given up arguing with your because it's so
fruitless.  Maybe we shouldn't have because that just seem to reaffirm
you in your personal universe.
