Subject: linux-next: manual merge of the kselftest tree with the block tree

Hi all,

Today's linux-next merge of the kselftest tree got a conflict in:

  tools/testing/selftests/ublk/kublk.h

between commit:

  584709ad5ce35 ("selftests: ublk: replace assert() with ublk_assert()")

from the block tree and commit:

  3e6ad272bb8b3 ("kselftest/kublk: include message in _Static_assert for C11 compatibility")

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.
