Dear Vinmenon,

I found a part of ION memory will be return to syste= m in android platform,

But these memorys can=1B$B!G=1B(Bt accounted i= n low-memory-killer strategy.

=1B$B!D=1B(B

And I also found ION memory comes from, kmalloc/vmal= loc/alloc pages/reserved memory.

What affect if account these memorys for free?<= /o:p>

Many thanks.

=1B$B!D=1B(B
