* librbd and librados include lttng tracepoints on distros with
liblttng 2.4 or later (only Ubuntu Trusty for the ceph.com
packages). When running a daemon that uses these libraries, i.e. an
application that calls fork(2) or clone(2) without exec(3), you must
set LD_PRELOAD=liblttng-ust-fork.so.0 to prevent a crash in the
lttng atexit handler when the process exits. The only ceph tool that
requires this is rbd-fuse.
