Hi Sudip,
This is correct, seems low-risk, and I don't mind it going ahead. But
I'm curious why you're interested in it for v4.14. Mostly, I wonder if
the same reason would apply to older kernels as well?
While the bugfix is applicable to v4.14, the nasty X crash on suspend is
only on v4.15 and v4.16. I think I left it to other's judgement, as to
whether the bugfix would be wanted outside that case.
IIUC, the bugfix could be applied to *three* of the "longterm" kernel
lines: 4.14.56, 4.9.113, 4.4.142. Since the commit says this bug was
introduced to the single-queue block layer in v4.4, commit 3ef28e8
("block: generic request_queue reference counting").
