Re: [RFCv2][PATCH 1/2] fs proc: make pagemap a privileged interface

Just a quick plea here to request that the final solution make it not
too hard for my error injection test programs to find physical addresses
to pass to EINJ driver. Tests already run as root - I can fix them to
also grab some CAP_* permission too if needed. I also don't mind
having to reboot the kernel to add a command line option to make
real page numbers appear. But I don't want to have to rebuild a kernel,
or get stuck using an old kernel.
