allocated slabs and bucket caches for free items. It will not go ask the vm for pages. This differs from M_NOWAIT in that it not only doesn't block, it doesn't even ask. - Add a new zcreate option ZONE_VM, that sets the BUCKETCACHE zflag. This tells uma that it should only allocate buckets out of the bucket cache, and not from the VM. It does this by using the M_NOVM option to zalloc when getting a new bucket. This is so that the VM doesn't recursively enter itself while trying to allocate buckets for vm_map_entry zones. If there are already allocated buckets when we get here we'll still use them but otherwise we'll skip it. - Use the ZONE_VM flag on vm map entries and pv entries on x86. |
