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 were required to support arbitrary range zeroing with-in a page. - This patch series also fixes the issue where "truncate -s 512 foo.txt" will fail if first sector of file is poisoned. Currently it succeeds and filesystem expectes whole of the filesystem block to be free of poison at the end of the operation. Christoph, I have dropped your Reviewed-by tag on 1-2 patches because these patches changed substantially. Especially signature of of dax zero_page_range() helper.
