    scsi: Silence unnecessary warnings about ioctl to partition · 6d935928
    Jan Kara authored
    Sometimes, warnings about ioctls to partition happen often enough that they
    form majority of the warnings in the kernel log and users complain. In some
    cases warnings are about ioctls such as SG_IO so it's not good to get rid of
    the warnings completely as they can ease debugging of userspace problems
    when ioctl is refused.
    Since I have seen warnings from lots of commands, including some proprietary
    userspace applications, I don't think disallowing the ioctls for processes
    with CAP_SYS_RAWIO will happen in the near future if ever. So lets just
    stop warning for processes with CAP_SYS_RAWIO for which ioctl is allowed.
