Subject: [PATCH 33/38] perf tools: Add missing_threads rb tree
Date: Tue, 3 Mar 2015 12:07:45 +0900 [thread overview]
Message-ID: <1425352070-1115-34-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1425352070-1115-1-git-send-email-namhyung@kernel.org>
Sometimes it's possible to miss certain meta events like fork/exit and
in this case it can fail to find such thread in the machine's rbtree.
But adding a thread to the tree is dangerous since it's now executed
in multi-thread environment otherwise it'll add an overhead in order
to grab a lock for every search. So adds a separate missing_threads
tree and protect it with a mutex. It's expected to be accessed only
if a thread is not found in a normal tree.
