Sorry the subject should say "Modules changes".
I also forgot to itemize possible merge conflicts and resolutions
which linux-next reported:
powerpc:
https://lkml.kernel.org/r/20220520154055.7f964...@canb.auug.org.au
kbuild:

OK, finally some changes for modules. It is still pretty boring,
but I am hopefull that the cleanup will yield nice results in the
future as further cleanups will make the code much easier to
read, maintain and test. Perhaps the most exciting thing is

Queued onto modules-testing! BTW I just had to rebase the change
with the kdb changes, it was a trivial change.

There goes the abstraction, so why not make this clear where we re-use
the struct module_signature for various things and call it as it is,
verify_mod_appended_signature() or some such?

We know we don't need del_gendisk() if we haven't added
the disk, so just skip it. This should fix a bug on older
kernels, as del_gendisk() became able to deal with
disks not added only recently, after the patch titled
"block: add flag for add_disk() completion notation".

care and use test_and_set_bit() because it is protects against
two nvme paths simultaneously calling device_add_disk() on the

The probably of that issue happening is low though, like

We manually unwind in case of add_disk() failure prior

new register_sysctl_subdir() helper. This removes the clutter from
kernel/sysctl.c.
