This patchset is attempt to add CoW support for fsdax, and take XFS,
which has both reflink and fsdax feature, as an example.
Changes from V1:
- Factor some helper
This patchset is attempt to add CoW support for fsdax, and take XFS,
which has both reflink and fsdax feature, as an example.
Changes from V1:
- Factor some helper functions to simplify dax fault code
- Introduce iomap_apply2() for dax_dedupe_file_range_compare()
- Fix mistakes and other
16 matches
