[PATCH 3/3] lustre: lov: Drop rq_buflen field

From: Julia Lawall
Date: Mon Jun 08 2015 - 09:03:09 EST


The rq_buflen field of the lov_request structure is never initialized. It
is only used in the free of req->rq_oi.oi_md in lov_finish_set. But no
oi_md field is ever initialized to the result of calling OBD_ALLOC_LARGE.
So it seems that the call to OBD_FREE_LARGE in lov_finish_set and the
rq_buflen in the lov_request structure are simply not needed.
