Hi Shuah,
Today's linux-next merge of the kselftest tree got a conflict in:
tools/testing/selftests/bpf/Makefile
between commit:
d498f8719a09 ("bpf: Rebuild bpf.o for any dependency update")
from the net-next tree and commit:
88baa78d1f31 ("selftests: remove duplicated all and clean target")
from the kselftest 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.
