Subject: [RFC PATCH 4/9] stacktrace: export-GPL stack_trace_save_user
Date: Thu, 9 Apr 2020 15:35:38 -0400 [thread overview]
Message-ID: <20200409193543.18115-5-mathieu.desnoyers@efficios.com> (raw)
In-Reply-To: <20200409193543.18115-1-mathieu.desnoyers@efficios.com>
The stack_trace_save symbol is already exported GPL. Add a GPL export
for the stack_trace_save_user symbol as well.
This is useful for tracers implemented as kernel modules.
