Modified files:
sys/vm uma_core.c uma_int.h
Log:
Fix the calculation that determines uz_maxpages. It was off for large zones.
Fortunately we have no large zones with maximums specified yet, so it wasn't
breaking anything.
Implement blocking when a zone exceeds the maximum and M_WAITOK is specified.
Previously this just failed like the old zone allocator did. The old zone
allocator didn't support WAITOK/NOWAIT though so we should do what we
advertise.
While I was in there I cleaned up some more zalloc logic to further simplify
that code path and reduce redundant code. This was needed to make the blocking
work properly anyway.
