Subject: [PATCH v5 0/8] dax/pmem: Provide a dax operation to zero range of memory
Date: Tue, 18 Feb 2020 16:48:33 -0500	[thread overview]
Message-ID: <20200218214841.10076-1-vgoyal@redhat.com> (raw)

Hi, 

This is V5 of patches. These patches are also available at.

https://github.com/rhvgoyal/linux/commits/dax-zero-range-v5

Changes since V4:

- Rebased on top of 5.6-rc2
- Added a separate patch so that pmem_clear_poison() accepts arbitrary
  offset and len and aligns these as needed. This takes away the burden
  of aligning from callers.

Previous versions of patches are here.

Thanks
