[PATCH] uapi: update install list after nvme.h rename

[PATCH] uapi: update install list after nvme.h rename

[Mike Frysinger]

Commit 9d99a8dda154 ("nvme: move hardware structures out of the uapi
version of nvme.h") renamed nvme.h to nvme_ioctl.h, but the uapi list
still refers to nvme.h.  People trying to install the headers hit a
failure as the header no longer exists.

Wouldn't reverting the rename be nicer to userspace? So that the
filename is preserved and anybody who #included nvme.h still can do so?

i have no opinion on either route

on a related note, shouldn't headers install be part of the automatic
kernel checks that are run against repos on kernel.org ?  who runs that
thing ?

I have been thinking about at least 'test -f' for all 'headers-y'
during make all. What do you think, Michal?

^^^^^

You have Fengguang's 0-day build robot on your mind? (CCed)

Can someone with authority please decide on what to do about this? 
It's wrecking havoc in userspace right now on stuff that needs nvme.h.

We can't build efivar in Debian unstable or Ubuntu xenial anymore. 
efivar used to build against kernels older than 4.4.0 no problem, then
this happened and because nvme_ioctl.h isn't installed properly you
can't even fix it by #include nvme_ioctl.h.
Consequently it's impossible to fix unless you do something ugly like
define the macro you need from nvme_ioctl.h in your source.

Fedora has pulled this patch in already in advance of it hitting -stable
so that they could build efivar and similar apps with a fix like this:
https://github.com/rhinstaller/efivar/commit/3a0ae7189fe96355d64dc2daf91cf85282773c66

The whole point of -stable is to avoid distros needing to pull stuff in
that really should benefit everyone..

So please:
* Either pull this commit into stable so that the correct headers are
installed at kernel build.
Or
* Revert the old commit (9d99a8dda154) in 4.4 stable so things can build
again.

The patch is in Linus' tree, and it was marked stable as well. So stable 
will pick it up, when the next 4.4-stable is spun.

I'm pretty sure I acked this when someone (usually Geert picks this up)
sent it earlier.  But it still looks fine:
