Hmm, I thought the conflusion was that it can be more, which is why
you proposed to increase it if the PAGE_SIZE is >= 64k. And based on
Jon's report at least for his tegra setups it works with 64k.
There is a workaround in that case to split to 32KiB chunks
Which I guess is less optimal than just using the block layer
splitting? Maybe add a big fat comment explaining this?
Improving it looks straight forward, but then there is testing and
checking the code for anything that might be assuming an sg element
is not more than 64KiB.
However it doesn't seem to offer any benefit, so it is difficult to
justify doing.
Did we come to any agreement on how to fix this?
Thanks
Jon
