Subject: [RFC v2 10/10] nvme: enable LBS support
Date: Fri, 15 Sep 2023 14:32:54 -0700 [thread overview]
Message-ID: <20230915213254.2724586-11-mcgrof@kernel.org> (raw)
In-Reply-To: <20230915213254.2724586-1-mcgrof@kernel.org>
Now that the block device cache allows LBS, and we have buffered-io
support, and we support both buffer-heads and iomap aops on the
block device cache through the inode dynamically, enable support for
LBA formats > PAGE_SIZE.
