Subject: [PATCH v4 20/27] x86: ftrace, mark function_hook as function
Date: Mon, 2 Oct 2017 11:12:39 +0200 [thread overview]
Message-ID: <20171002091246.28432-20-jslaby@suse.cz> (raw)
In-Reply-To: <20171002091246.28432-1-jslaby@suse.cz>
Relabel function_hook to be marked really as a function. It is called
from C and has the same expectations towards the stack etc.
