Subject: [PATCH 07/15] selftests/seccomp: Remove syscall setting #ifdefs
Date: Sat, 12 Sep 2020 04:08:12 -0700 [thread overview]
Message-ID: <20200912110820.597135-8-keescook@chromium.org> (raw)
In-Reply-To: <20200912110820.597135-1-keescook@chromium.org>
With all architectures now using the common SYSCALL_NUM_SET() macro, the
arch-specific #ifdef can be removed from change_syscall() itself.
