Peter Xu a308c71bf1 mm/gup: Remove enfornced COW mechanism ... With the more strict (but greatly simplified) page reuse logic in do_wp_page(), we can safely go back to the world where cow is not enforced with writes. This essentially reverts commit 17839856fd ("gup: document and work around 'COW can break either way' issue"). There are some context differences due to some changes later on around it: 2170ecfa76 ("drm/i915: convert get_user_pages() --> pin_user_pages()", 2020-06-03) 376a34efa4 ("mm/gup: refactor and de-duplicate gup_fast() code", 2020-06-03) Some lines moved back and forth with those, but this revert patch should have striped out and covered all the enforced cow bits anyways.
