Subject: [PATCH 5/5] mm, slab_common: Make initializing KMALLOC_DMA start from 1
Date: Wed,  4 Sep 2019 00:04:30 +0800	[thread overview]
Message-ID: <20190903160430.1368-6-lpf.vector@gmail.com> (raw)
In-Reply-To: <20190903160430.1368-1-lpf.vector@gmail.com>

kmalloc_caches[KMALLOC_NORMAL][0] will never be initialized,
so the loop should start at 1 instead of 0
