Subject[patch 6/6][RFC] Drop CAP_SYS_RAWIO requirement on FIBMAP
Remove the need for having CAP_SYS_RAWIO when doing a FIBMAP call on an open file descriptor.

It would be nice to allow users to have permission to see where their data is landing on disk, and there really isn't a good reason to keep them from getting at this information.
