Subject: Re: [PATCH 05/14] xfs: implement iomap based buffered write path
Date: Thu, 5 May 2016 13:55:14 -0400 (EDT) [thread overview]
Message-ID: <1826465730.2008964.1462470914901.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <1462310947-16132-6-git-send-email-hch@lst.de>
----- Original Message -----
> Convert XFS to use the new iomap based multipage write path. This involves
> implementing the ->iomap_begin and ->iomap_end methods, and switching the
> buffered file write, page_mkwrite and xfs_iozero paths to the new iomap
> helpers.
>
> With this change __xfs_get_blocks will never be used for buffered writes,
> and the code handling them can be removed.
>
> Based on earlier code from Dave Chinner.
