Message-ID: <82b7680a2e3f85685950ac288534b8c6575bcd63.1535734192.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.29.git.gitgitgadget@gmail.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Add trace2_region_enter() and _leave() around the entire preload_index()
call.  Also add thread-specific events in the preload_thread() threadproc.
