Hi all,
Today's linux-next merge of the rust tree got conflicts in:
Makefile
scripts/Makefile.modfinal
between commit:
9741e07ece7c ("kbuild: Unify options for BTF generation for vmlinux and modules")
from Linus' tree and commit:
fcd48fa27403 ("Kbuild: add Rust support")
from the rust tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
