Subject: [PATCH v2 41/84] staging/lustre: Reformat comments and structures in lustre_idl.h
From: Oleg Drokin <green@...uxhacker.ru>
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.
