Subject: [PATCH 2/3] stacktrace: Remove superfluous WARN_ONCE() from save_stack_trace_tsk_reliable()
Date:   Wed, 24 Apr 2019 10:55:49 +0200
Message-Id: <20190424085550.29612-3-pmladek@suse.com>
In-Reply-To: <20190424085550.29612-1-pmladek@suse.com>
References: <20190424085550.29612-1-pmladek@suse.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

WARN_ONCE() in the generic save_stack_trace_tsk_reliable() is superfluous.
The only current user klp_check_stack() writes its own warning when
-ENOSYS is returned.
