static inline void check_highest_zone(enum zone_type k) { - if (k > policy_zone && k != ZONE_MOVABLE) + if (k > policy_zone && k != ZONE_MOVABLE && !is_zone_cma_idx(k)) policy_zone = k; }Should we apply policy to allocation from ZONE CMA ?. CMA reserve happens early and may mostly come from one node. Do we want the CMA allocation to fail if we use mbind(MPOL_BIND) with a node mask not including that node on which CMA is reserved, considering CMA memory is going to be used for special purpose.
Looking at this again, I guess CMA alloc is not going to depend on memory policy, but this is for other movable allocation ? -aneesh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
