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

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" as suggested[1].

Changes from previous V3:
 - Rebased on v5.13
 - Add Darrick's Reviewed-by

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 v5.13)
