[PATCH net-next 15/15] selftests: mptcp: use KSFT_SKIP/KSFT_PASS/KSFT_FAIL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

This patch uses the public var KSFT_SKIP in mptcp_lib.sh instead of
ksft_skip, and drop 'ksft_skip=4' in mptcp_join.sh.

Use KSFT_PASS and KSFT_FAIL macros instead of 0 and 1 after 'exit '
and 'ret=' in all scripts:

        exit 0 -> exit ${KSFT_PASS}
        exit 1 -> exit ${KSFT_FAIL}
         ret=0 ->  ret=${KSFT_PASS}
         ret=1 ->  ret=${KSFT_FAIL}
