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).
Use the recently introduced guard(mutex) infrastructure acquire and
automatically release vendor_module_lock when the guard goes out of
scope.
Drop the inner __kvm_x86_vendor_init(), its sole purpose was to simplify
releasing vendor_module_lock in error paths.
No functional change intended.
the the underscore version doesn't have any other callers.
Has this fallen through the cracks as I don't see it in 6.7?
