Subject: [PATCH v4 2/2] drivers/base/memory.c: Rename the misleading parameter
Date: Fri, 29 Mar 2019 17:36:59 +0800 [thread overview]
Message-ID: <20190329093659.GG7627@MiWiFi-R3L-srv> (raw)
In-Reply-To: <20190329082915.19763-2-bhe@redhat.com>
The input parameter 'phys_index' of memory_block_action() is actually
the section number, but not the phys_index of memory_block. This is
a relict from the past when one memory block could only contain one
section.
Rename it to start_section_nr.
