Nothing requires that clamp() return a constant expression.
The logic to do so significantly increases the .i file.
Remove the check and directly expand __clamp_once() from clamp_t()
since the type check can't fail.

like this:
[1m][ 512k ]
^0 ^256^384
Assume we call filemap_get_folios_contig() and get back the first folio
and get start_idx=256
Then, someone fallocate(PUNCH_HOLE) the whole range and re-populates the
whole range with a 2m folio.
[ 2m ]
^0 ^256^384
if we call filemap_get_folios_contig() with 256, we get another "large
folio with offset".
Of course, we can detect that, and simply fail/retry. Just wondering if
that could happen.

Thanks, David
Hello,
I have a draft of a proposal that I would like feedback on from Maíra
Canal (or another mentor). If you could please let me know their email
address (or I could send you the draft and you could forward it to them).
It's for the KUnit and DRM project.
Thanks,
David Walters.

ich they were created is the right thing to do.
It looks like, from the comments on patch 3, this may no longer be
necessary? Is that so?
Otherwise, if you have a real use case for it, I've no objection to
KUnit adding this as a feature (though I'd probably add some
