Subject: [PATCH v3 0/7] dax,pmem: Provide a dax operation to zero range of memory 
Date: Fri,  7 Feb 2020 15:26:45 -0500
Message-ID: <20200207202652.1439-1-vgoyal@redhat.com> (raw)

Hi,

This is V3 of patches. I have dropped RFC tag from the series as it
looks like there is agreement on the interface. These patches are also
available at.

https://github.com/rhvgoyal/linux/commits/dax-zero-range-v3

I posted previous versions here.

v2:
https://lore.kernel.org/linux-fsdevel/20200203200029.4592-1-vgoyal@redhat.com/
v1:
https://lore.kernel.org/linux-fsdevel/20200123165249.GA7664@redhat.com/

Changes since V2:

Primarily took care of comments from Christoph.

- Changed zero_copy_range() parameters to pass dax device offset as u64.
- Fixed comment which says current interface only supports zeroing
  with-in page.
- Refactored pmem_do_bvec() and reused write side of code in
  zero_page_range().
- Removed generic_dax_zero_page_range()
- Fixed s390 dcssblk.c compilation issue.

Please review. 

Thanks
Vivek
