Subject: [PATCH v3 0/3] fsdax: Factor helper functions to simplify the code

From: Shiyang Ruan <ruansy.fnst@...fujitsu.com>

The page fault part of fsdax code is little complex. In order to add CoW
feature and make it easy to understand, I was suggested to factor some
helper functions to simplify the current dax code.

This is separated from the previous patchset called "V3 fsdax,xfs: Add
reflink&dedupe support for fsdax", and the previous comments are here[1].

Changes from V2:
 - fix the type of 'major' in patch 2
 - Rebased on v5.12-rc8

Changes from V1:
 - fix Ritesh's email address
 - simplify return logic in dax_fault_cow_page()

(Rebased on v5.12-rc8)
