[PATCH 41/56] staging/lustre: Reformat comments and structures in lustre_idl.h

From: green
Date: Mon Feb 22 2016 - 23:04:55 EST

From: Oleg Drokin <green@xxxxxxxxxxxxxx>

This file mostly contains various on the wire data and got
significantly mangled in transition.
This patch rectifies the situation somewhat. Also fixes the
comment style for block comments.
