| Subject: selftests/x86/syscall_nt: Clear weird flags after each test |
| |
| 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. |
