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.
