Subject: relayd: track the live viewer worker thread's epoll fd
X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=35bc1f58f7076171ab8957c2472b056fa9c6ea60

relayd: track the live viewer worker thread's epoll fd

Create the live worker threads' epoll fd through the
fd_tracker_util_poll_create() util. This causes the resulting fd
(in epoll mode) to be tracked by the fd tracker.
