[lustre-devel] [PATCH 1/7] staging: lustre: lcommon_cl.c: replace container_of0 by container_of

[Aya Mahfouz]

Replaces container_of0 by container_of. The only difference between
the two implementations is that container_of0 tries to evade
type casting if the pointer is erroneous or null. The use of
container_of is encouraged to bring lustre one step closer to
community standards.
