Subject: [PATCH v4 0/3] mm/mprotect: Fix soft-dirty checks

v4:
- Add r-bs
- Fix spellings and commit messages (on Fixes) [David]
- In the new test case unlink() after open() to not leave temp file even failed

v2: https://lore.kernel.org/lkml/20220720220324.88538-1-peterx@redhat.com
v3: https://lore.kernel.org/lkml/20220721183338.27871-1-peterx@redhat.com

Patch 1 is the previous patch and real fix.  Two more test patches added to
add mprotect test to soft-dirty.c, meanwhile add soft-dirty test into the
vm test loop.

Please review, thanks.
