Subject: [PATCH] mm/vmscan.c: Clean code by removing unnecessary assignment
Date: Sat, 29 Feb 2020 22:40:22 +0100	[thread overview]
Message-ID: <20200229214022.11853-1-mateusznosek0@gmail.com> (raw)

From: Mateusz Nosek <mateusznosek0@gmail.com>

Previously 0 was assigned to variable 'lruvec_size',
but the variable was never read later.
So the assignment can be removed.
