Subject: iomap based DAX path V2
Date: Wed, 14 Sep 2016 12:01:19 +0200	[thread overview]
Message-ID: <1473847291-18913-1-git-send-email-hch@lst.de> (raw)

This series adds a DAX I/O path based on the iomap interface.  This
allows more efficient block mapping including defined hole semantics,
and is an important step toward getting rid of buffer_heads in XFS.

Changes since V1:
 - added a conversion of ext2 to the iomap interface
 - addresse feedback from Ross, Dave and Robert
