Subject: [PATCH] seccomp.2: Clarify SECCOMP_RET_KILL kills tasks not processes
Date: Thu, 6 Jul 2017 12:23:07 -0700	[thread overview]
Message-ID: <20170706192307.GA38040@beast> (raw)

Zach Reizner pointed out a mismatch between kernel behavior and the
man-page documentation of SECCOMP_RET_KILL which kills tasks not
processes.
