Any ideas about why other arches don't encouter the problem? jeff 2002/06/19 13:49:44 PDT Modified files: sys/vm uma.h uma_core.c Log: - Remove bogus use of kmem_alloc that was inherited from the old zone allocator. - Properly set M_ZERO when talking to the back end page allocators for non malloc zones. This forces us to zero fill pages when they are first brought into a cache. - Properly handle M_ZERO in uma_zalloc_internal. This fixes a problem where per cpu buckets weren't always getting zeroed.
