Thanks, did a scratch build for that and dropped it in the bug. Only
one user has reported back, but the report was that it did not fix the
issue.  I have also gotten confirmation now that the issue is occuring
with 5.16-rc2.

Okay.

Morning light brings clarity to the mind.  Here's a patch that should
definitely fix this bug, as well as the very unlikely race of the page
being truncated from the page cache before pipe_buf_release() is
called.

Please test.

Thanks,
