But this intro is actively misleading. The double-underscore variant most definitely
isn't superfluous, e.g. it eliminates the need for gotos reduces the probability
of incorrect error codes, bugs in the error handling, etc. It _becomes_ superflous
after switching to guard(mutex).
IMO, this is one of the instances where the "problem, then solution" appoach is
counter-productive. If there are no objections, I'll massage the change log to
the below when applying (for 6.8, in a few weeks).
I think this is a "Speak Now or Forever Rest in Peace" situation. I'm
going to wait a couple days more for reviews to come in, post a v14
myself, and apply the series to kvm/next as soon as Linus merges the 6.7
changes. The series will be based on the 6.7 tags/for-linus, and when
6.7-rc1 comes up, I'll do this to straighten the history:
git checkout kvm/next
git tag -s -f kvm-gmem HEAD
git reset --hard v6.7-rc1
git merge tags/kvm-gmem
# fix conflict with Christian Brauner's VFS series
git commit
git push kvm
6.8 is not going to be out for four months, and I'm pretty sure that
anything discovered within "a few weeks" can be applied on top, and the
heaviness of a 35-patch series will outweigh any imperfections by a long
margin).
(Full disclosure: this is _also_ because I want to apply this series to
the RHEL kernel, and Red Hat has a high level of disdain for
non-upstream patches. But it's mostly because I want all dependencies
to be able to move on and be developed on top of stock kvm/next).
