Subject: [PATCH bpf-next 3/4] tools/resolve_btfids: Set srctree variable unconditionally
Date: Thu,  4 Feb 2021 22:18:24 +0100	[thread overview]
Message-ID: <20210204211825.588160-4-jolsa@kernel.org> (raw)
In-Reply-To: <20210204211825.588160-1-jolsa@kernel.org>

We want this clean to be called from tree's root Makefile,
which defines same srctree variable and that will screw
the make setup.

We actually do not use srctree being passed from outside,
so we can solve this by setting current srctree value
directly.

Also root Makefile does not define the implicit RM variable,
so adding RM initialization.
