Subject: [RFC PATCH 0/7] xfs: add reflink & dedupe support for fsdax.
Date: Wed, 31 Jul 2019 19:49:28 +0800
Message-ID: <20190731114935.11030-1-ruansy.fnst@cn.fujitsu.com> (raw)

This patchset aims to take care of this issue to make reflink and dedupe
work correctly in XFS.

It is based on Goldwyn's patchsets: "v4 Btrfs dax support" and "Btrfs
iomap".  I picked up some patches related and made a few fix to make it
basically works fine.

For dax framework: 
  1. adapt to the latest change in iomap.

For XFS:
  1. report the source address and set IOMAP_COW type for those write
     operations that need COW.
  2. update extent list at the end.
  3. add file contents comparison function based on dax framework.
  4. use xfs_break_layouts() to support dax.


Goldwyn Rodrigues (3):
  dax: replace mmap entry in case of CoW
  fs: dedup file range to use a compare function
  dax: memcpy before zeroing range

Shiyang Ruan (4):
  dax: Introduce dax_copy_edges() for COW.
  dax: copy data before write.
  xfs: Add COW handle for fsdax.
  xfs: Add dedupe support for fsdax.
