Hi,
This is V6 of patches. These patches are also available at.
Changes since V5:
- Dan Williams preferred ->zero_page_range() to only accept PAGE_SIZE
aligned request and clear poison only on page size aligned zeroing. So
I changed it accordingly.
- Dropped all the modifications which wer
This patch adds support for dax zero_page_range operation to dm targets.

Add a helper dax_ioamp_zero() to zero a range. This patch basically
merges __dax_zero_page_range() and iomap_dax_zero().

Use new dax native zero page method for zeroing page if I/O is page
aligned. Otherwise fall back to direct_access() + memcpy().
This gets rid of one of the depenendency on block device in dax path.

Add a dax operation zero_page_range, to zero a page. This will also clear any
known poison in the page being zeroed.
As of now, zeroing of one page is allowed in a single call. There
are no callers which are trying to zero more than a page in a single call.
Once we grow the callers which zero more
This splits pmem_do_bvec() into pmem_do_read() and pmem_do_write().
pmem_do_write() will be used by pmem zero_page_range() as well. Hence
sharing the same code.
