You can probably use upper_32bits() here...
Where is that defined? I'd be glad to use it. -Alex
include/linux/kernel.h, and it is upper_32_bits() and lower_32_bits()
sorry about the missing space.
That's nice. I'll still use a separate commit (and will
credit you with the suggestion) but it will be much smaller.
Thanks. I'll post v2 shortly.
