Subject: [PATCH 2/4] perf tools: Mark ksymbol dsos with kernel type
Date: Mon, 10 Feb 2020 15:32:16 +0100	[thread overview]
Message-ID: <20200210143218.24948-3-jolsa@kernel.org> (raw)
In-Reply-To: <20200210143218.24948-1-jolsa@kernel.org>

We add ksymbol map into machine->kmaps, so it needs to be
created as 'struct kmap', which is dependent on its dso
having kernel type.
