Hi I found the freed reserved memory by free_initrd_mem( ) and cma_activate_area( ) Are still marked as reserved in /sys/kernel/debug/memblock/reserved . I think This is not correct and not suitable for memory debug, Why not also call memblock_free during these functions? So that /sys/kernel/debug/memblock/reserved only mark really reserved memory as reserved . Thanks. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
