Subject: [PATCH v5 2/3] asm-generic: Add generic seccomp.h for secure computing mode 1
Date: Tue, 22 Jul 2014 18:14:58 +0900	[thread overview]
Message-ID: <1406020499-5537-3-git-send-email-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <1406020499-5537-1-git-send-email-takahiro.akashi@linaro.org>

Those values (__NR_seccomp_*) are used solely in secure_computing()
to identify mode 1 system calls. If compat system calls have different
syscall numbers, asm/seccomp.h may override them.

Acked-by: Arnd Bergmann <arnd@arndb.de>
