Subject: [PATCH] tools lib bpf: Fix double file test in Makefile
Date: Tue, 15 Aug 2017 11:33:30 -0500 [thread overview]
Message-ID: <1502814810-960-1-git-send-email-daniel.diaz@linaro.org> (raw)
The Makefile verifies the same file exists twice:
test -f ../../../include/uapi/linux/bpf.h -a \
-f ../../../include/uapi/linux/bpf.h
The purpose of the check is to ensure the diff (immediately
after the test) doesn't fail with these two files:
/tools/include/uapi/linux/bpf.h
/include/uapi/linux/bpf.h
Same recipe for bpf_common:
test -f ../../../include/uapi/linux/bpf_common.h -a \
-f ../../../include/uapi/linux/bpf_common.h
This corrects the location of the tests.
