Subject: [PATCH] trace: add missing forward declaration
Date: Mon, 16 Apr 2018 10:36:25 +0800 [thread overview]
Message-ID: <20180416023626.139915-1-cwahbong@google.com> (raw)
Without this forward declaration compile may fail if this header is
included only for registering other probe event without struct
pool_workqueue.
