Subject: FW: Arch/arm/msm/memory.c:reserve_memory_for_mempools( )

Hi Sboy,

I don't know who should I send this mail to .
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.

Thanks
