I don't think your merge is correct.

I pushed out mine.

So the differences are (apart from purely newline changes):

 - you kept the early "flush_work(&dev->reset_work)", so your merge
didn't take the changes from commit
ff23a2a15a2117245b4599c1352343c8b8fb4c43 properly, and you flush the
work twice.

   I don't know that it matters, but it looks odd.

 - Your merge dropped the nvme_dev_disable() from
nvme_remove_dead_ctrl(), added by commit
69d9a99c258eb1d6478fd9608a2070890797eed7

 - Your merge kept the redundant dev_set_drvdata() in
nvme_init_ctrl(), removed by commit
f4f0f63e6f01055dfbdb7bc5e83935e1bdfa1980.

Anyway, since I got a different merge result than you did, you should
double-check, but I think I did the merge correctly.

But I don't know the code nor the hardware, so I'm just going by
reading the commits.

I also do have to ask: why the hell is nvme development done in that
insane way? Why the f*ck can people not work together? Why are these
two different groups messing with each others code?

Tell them to stop.

I'm not happy with how messy these block layer pulls are.
