I haven't tried to apply the whole series to the 3.19.1 which I'm 
currently using. As mentioned before, something (a single patch I've 
tried before) didn't apply cleanly which means I need to have a deeper 
look at the stuff. E.g. I've just learned (through another problem), 
that (my version of) glibc still doesn't use the aio-syscalls the kernel 
provides (and instead uses pread/pwrite).

I will look if I find the time today.
