If you are not the right person, please forward To the right responsible person , Thank you ! I have a question about msm kernel code : File: Arch/arm/msm/memory.c reserve_memory_for_mempools() it call memblock_remove() directly, I think it's not safe sometimes , Should use arm_memblock_steal() function or some other similar Function to make sure the removed memory is not reserved by memblock driver, In case the removed memory is reserved by some other driver.
