    Subject[PATCH 4.14 140/166] selftests/x86/syscall_nt: Clear weird flags after each test
    Date
    From: Andy Lutomirski <luto@kernel.org>

    [ Upstream commit a61fa2799ef9bf6c4f54cf7295036577cececc72 ]

    Clear the weird flags before logging to improve strace output --
    logging results while, say, TF is set does no one any favors.
