Subject: [PATCH 2/2] kbuild: do not remove empty *.symtypes explicitly
Date: Tue, 29 Mar 2022 11:15:20 +0900 [thread overview]
Message-ID: <20220329021520.308997-2-masahiroy@kernel.org> (raw)
In-Reply-To: <20220329021520.308997-1-masahiroy@kernel.org>
Presumably, 'test -s $@ || rm -f $@' intends to remove the output when
the genksyms command fails.
It is unneeded because .DELETE_ON_ERROR automatically removes the output
on failure.
