Subject: [PATCH v2 06/11] x86/unwind/orc: Convert global variables to static
Date: Sat, 25 Apr 2020 05:03:05 -0500	[thread overview]
Message-ID: <43ae310bf7822b9862e571f36ae3474cfde8f301.1587808742.git.jpoimboe@redhat.com> (raw)
In-Reply-To: <cover.1587808742.git.jpoimboe@redhat.com>

These variables aren't used outside of unwind_orc.c, make them static.

Also annotate some of them with '__ro_after_init', as applicable.
