Subject: [PATCH 11/16] perf: purge all maps from the names tree
Date: Sat, 16 Mar 2019 16:05:51 +0800 [thread overview]
Message-ID: <20190316080556.3075-12-changbin.du@gmail.com> (raw)
In-Reply-To: <20190316080556.3075-1-changbin.du@gmail.com>
Add function __maps__purge_names() to purge all maps from the names tree.
We need to cleanup the names tree in maps__exit().
