Subject: qa: make rbd-fuse exit cleanly with lttng
X-Git-Tag: v0.94~32^2~1
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=918afc0a58fc40a4beedfcadb8046b8ca88ccf11;p=ceph.git

qa: make rbd-fuse exit cleanly with lttng

lttng requires daemons (things that call fork, clone, or daemon
without exec, like fuse) to use a LD_PRELOAD library. Without this,
the lttng atexit() handler crashes.
