| H A D | uma.h | diff 247360 Tue Feb 26 21:38:56 MST 2013 attilio Merge from vmc-playground branch: Replace the sub-optimal uma_zone_set_obj() primitive with more modern uma_zone_reserve_kva(). The new primitive reserves before hand the necessary KVA space to cater the zone allocations and allocates pages with ALLOC_NOOBJ. More specifically: - uma_zone_reserve_kva() does not need an object to cater the backend allocator. - uma_zone_reserve_kva() can cater M_WAITOK requests, in order to serve zones which need to do uma_prealloc() too. - When possible, uma_zone_reserve_kva() uses directly the direct-mapping by uma_small_alloc() rather than relying on the KVA / offset combination. The removal of the object attribute allows 2 further changes: 1) _vm_object_allocate() becomes static within vm_object.c 2) VM_OBJECT_LOCK_INIT() is removed. This function is replaced by direct calls to mtx_init() as there is no need to export it anymore and the calls aren't either homogeneous anymore: there are now small differences between arguments passed to mtx_init().
