See GetHugePageSize(). */ I don't know what "recent enough" is in this context, but evidently RHEL7 isn't it (no surprise considering that's a trailing-edge distro at this point). I don't find it surprising that the authors of this feature didn't try to document exactly which Linux versions it can be used on. Keeping such documentation accurate would be a nightmare. regards, tom lane
