Subject: [patch V5 01/15] seccomp: Provide stub for __secure_computing()
Date: Wed, 22 Jul 2020 23:59:55 +0200 [thread overview]
Message-ID: <20200722220519.404974280@linutronix.de> (raw)
In-Reply-To: <20200722215954.464281930@linutronix.de>
From: Thomas Gleixner <tglx@linutronix.de>
To avoid #ifdeffery in the upcoming generic syscall entry work code provide
a stub for __secure_computing() as this is preferred over
secure_computing() because the TIF flag is already evaluated.
