Subject: [PATCH 3/4] perf tools: Fix map__clone for struct kmap
Date: Mon, 10 Feb 2020 15:32:17 +0100 [thread overview]
Message-ID: <20200210143218.24948-4-jolsa@kernel.org> (raw)
In-Reply-To: <20200210143218.24948-1-jolsa@kernel.org>
The map__clone function can be called on kernel maps
as well, so it needs to duplicate the whole kmap data.
