Subject: [patch 087/166] mm/mm_init.c: clean code. Use BUILD_BUG_ON when comparing compile time constant
Date: Mon, 06 Apr 2020 20:08:36 -0700 [thread overview]
Message-ID: <20200407030836.Gjtk9qcWW%akpm@linux-foundation.org> (raw)
In-Reply-To: <20200406200254.a69ebd9e08c4074e41ddebaf@linux-foundation.org>
From: Mateusz Nosek <mateusznosek0@gmail.com>
Subject: mm/mm_init.c: clean code. Use BUILD_BUG_ON when comparing compile time constant
MAX_ZONELISTS is a compile time constant, so it should be compared using
BUILD_BUG_ON not BUG_ON.
