Subject: [RFC PATCH 0/7] xfs: add reflink & dedupe support for fsdax.
Date: Wed, 31 Jul 2019 19:49:28 +0800 [thread overview]
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.
