Subject: [patch 20/35] mm/memory_hotplug: rename mhp_restrictions to mhp_params
Date: Fri, 10 Apr 2020 14:33:21 -0700	[thread overview]
Message-ID: <20200410213321.S-XgeJDgS%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200410143047.bf34a933ce1affdc042c7c80@linux-foundation.org>

From: Logan Gunthorpe <logang@deltatee.com>
Subject: mm/memory_hotplug: rename mhp_restrictions to mhp_params

The mhp_restrictions struct really doesn't specify anything resembling a
restriction anymore so rename it to be mhp_params as it is a list of
extended parameters.
