patches below are an attempt to solve problems filesystems have with
page_mkwrite() when blocksize < pagesize (see the changelog of the second patch
for details).

It would be useful if you had a test case reproducing these issues,
so that I can verify how well your patches work in various scenarios.

  Good point, I should have mentioned in the changelog: fsx-linux is able
to trigger the problem quite quickly.
  I have also written a simple program for initial testing of the fix
(works only for 1K blocksize and 4K pagesize) - it's attached.
