Subject: osd: initialize class_handler of OSD properly
X-Git-Tag: ses5-milestone5~180^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=30cffa0653f7260618c5f8a3b56641e099b59c9a;p=ceph.git

osd: initialize class_handler of OSD properly

The destructor of OSD will delete class_handler arbitrarily
and there are cases we'll fail to start an osd before we
load the class_handler correctly.

So it is safe to initialize class_handler to NULL as to
avoid access violation.
