The fact that we need CAP_SYS_RAIO for FIBMAP is pretty silly, given that FIEMAP does not require privileges --- and in fact the preferred interface. Why not just simply drop the requirement for privileges for FIBMAP? (Seth, Serge, this isn't a real objection to your patch; but the fact that FIBMAP requires root has always been a bit silly, and this would be a great opportunity to simplify things a bit.) - Ted On Fri, Dec 04, 2015 at 01:11:43PM -0600, Serge E.
