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.
Shiyang,
I think you used the older patches which does not contain the iomap changes
which would call iomap_begin() with two iomaps. I have it in the btrfs-iomap
Oh, Sorry for my carelessness. This patchset is built on your "Btrfs
iomap". I didn't point it out in cover letter.
branch and plan to update it today. It is built on v5.3-rcX, so it should
contain the changes which moves the iomap code to the different directory.
I will build the dax patches on top of that.
However, we are making a big dependency chain here
Don't worry. It's fine for me. I'll follow your updates.
