Okay, I've written up my thoughts on this to the kernel community.
In summary, I don't see how FUSE can work reliably on ARM in its
current state, especially given the complexities of preemption etc.
I believe that using get_user_pages() to access the current processes
VM is always going to be racy and unreliable no matter how much cache
flushing you apply to the kernel.

Please direct further discussion on this topic to my mail on
linux-kernel.  Thanks.
