Subject: [PATCH 2/4] ftrace: drop 'static' qualifier from ftrace_ops_list_func()
Date:   Sat, 27 Apr 2019 12:06:37 +0200
Message-Id: <20190427100639.15074-3-nstange@suse.de>
In-Reply-To: <20190427100639.15074-1-nstange@suse.de>
References: <20190427100639.15074-1-nstange@suse.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

With an upcoming patch improving x86' ftrace_int3_handler() not to simply
skip over the insn being updated, ftrace_ops_list_func() will have to get
referenced from arch/x86 code. Drop its 'static' qualifier.
