Thanks. I have gone through the last patch this morning, did some
tests on all the platforms I have at hand (including Linux) and
finished by applying it after doing some small tweaks. First, I have
finished by extending GetHugePageSize() to accept NULL for its first
argument hugepagesize. A second thing was in the docs, where it is
still useful IMO to keep the reference to /proc/meminfo and
/sys/kernel/mm/hugepages to let users know how the system impacts the
calculation of the new GUC.
Let's see what the buildfarm thinks about it.
