Subject: [RFCv3 3/7] ext2: Enable large folio support
Date: Thu, 25 Apr 2024 18:58:47 +0530
Message-ID: <581b2ed21a709093522f3747c06e8171c82f2d8c.1714046808.git.ritesh.list@gmail.com>

Now that ext2 regular file buffered-io path is converted to use iomap,
we can also enable large folio support for ext2.
