Yeh, bisection, review, all the usual reasons for keep unrelated changes
split. I am not usually fanatic about splitting hairs on this, but the
mount api porting patch was already a big change that was hard for me to
review and it grew all those extra additions like redirect_mode which
were good changes, but not related, so I did this to make my own (and others)
review of your patches easier.

I am glad if we are all happy with the end result.

Thanks,
Amir.
