[sheepdog] [PATCH 0/6] employ LTTng for performance analysis and debugging

[Hitoshi Mitake]

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
