Subject: [PATCH v11 6/6] drivers: virtio_mem: use pageblock size as the minimum virtio_mem size.
Date: Mon, 25 Apr 2022 10:31:18 -0400 [thread overview]
Message-ID: <20220425143118.2850746-7-zi.yan@sent.com> (raw)
In-Reply-To: <20220425143118.2850746-1-zi.yan@sent.com>
From: Zi Yan <ziy@nvidia.com>
alloc_contig_range() now only needs to be aligned to pageblock_nr_pages,
drop virtio_mem size requirement that it needs to be MAX_ORDER_NR_PAGES.
