Subject: [PATCH] stacktrace: Remove superfluous WARN_ONCE() from save_stack_trace_tsk_reliable()
Date: Mon, 29 Apr 2019 16:56:24 +0200	[thread overview]
Message-ID: <20190429145624.27746-1-pmladek@suse.com> (raw)

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.
