I don't know which change you think you're referring to, but I suspect that
you mean PK's recent changes to the buffer cache code.

I just looked at that code again and I'm a bit curious about some aspects
of it -- such as the use of, essentially, different LRUs for buffers
of different sizes, which seems a bit bogus -- but I can't see how it
could possibly cause additional demand for *pageable* memory, which is
what would be necessary to cause an increase in swap utilization.

I think some other recent change must be causing your problem.
