Subject: [RFC PATCH v2 25/25] ext4: enable large folio for regular file with iomap buffered IO path
From: Zhang Yi <yi.zhang@...wei.com>
After we convert buffered IO path to iomap for regular files, we can
enable large foilo for them together, that should be able to bring a lot
of performance gains for large IO.
