ZRAM_HUGE flag doubles most significant bit in zram size.
I had an idea to redefine it, but do not fully understand how to do it correctly.
I'm sure that MSB = PAGE_SHIFT on BIG_ENDIAN but do not understand what's happen on LITTLE_ENDIAN?
Is MSB = 0 in this case? Could it have some other unpredictable value?
In any case I think we can always replace ZRAM_HUGE bit check by BIT(PAGE_SHIFT) test.
Thank you,
