LTTng is the de facto standard of tracing framework. This patchset
employes it for performance analysis and debugging of sheepdog. It
would be useful for analyzing bottlenecks.
Hitoshi Mitake (6):
configure: enable LTTng with --enable-lttng-ust option
sheep: use _exit(2) instead of exit(3) in lock_and_daemon() for gcc's
destructors
lib: add a header for a case of disabling LTTng
lib: add tracepoints related to work queue
lib: add tracepoints related to sockfd management
lib: add tracepoints related to event loop
