From: Oleg Drokin Date: Thu, 25 Feb 2016 03:00:24 +0000 (-0500) Subject: staging/lustre: Reformat comments and structures in lustre_idl.h X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a1e616b08e4aaac5b7c90de0c6cfda4cdc984506;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging/lustre: Reformat comments and structures in lustre_idl.h 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.
