Subject: [PATCH 2/2] mm/memmap_init: Update variable name in memmap_init_zone
Date: Thu, 26 Sep 2019 17:55:52 +0530
Message-ID: <20190926122552.17905-2-aneesh.kumar@linux.ibm.com> (raw)
In-Reply-To: <20190926122552.17905-1-aneesh.kumar@linux.ibm.com>

The third argument is actually number of pages. Changes the variable name
from size to nr_pages to indicate this better.

No functional change in this patch.
