Subject: [PATCH 5.11 41/45] kbuild: Do not clean resolve_btfids if the output does not exist
Date: Fri,  9 Apr 2021 11:54:07 +0200	[thread overview]
Message-ID: <20210409095306.738255512@linuxfoundation.org> (raw)
In-Reply-To: <20210409095305.397149021@linuxfoundation.org>

From: Jiri Olsa <jolsa@kernel.org>

[ Upstream commit 0e1aa629f1ce9e8cb89e0cefb9e3bfb3dfa94821 ]

Nathan reported issue with cleaning empty build directory:

  $ make -s O=build distclean
  ../../scripts/Makefile.include:4: *** \
  O=/ho...build/tools/bpf/resolve_btfids does not exist.  Stop.

The problem that tools scripts require existing output
directory, otherwise it fails.

Adding check around the resolve_btfids clean target to
ensure the output directory is in place.
