ioctl passthrough mechanism for Lustre OST/MDT mountpoints

    Description

      Implement an interface for sending IO Control (ioctl) commands from userspace through the Lustre mount point to the underlying ldiskfs filesystem to allow execution of filesystem-wide ioctl() commands, such as resize. This will allow user-space tools that operate via ioctl() commands on the filesystem mountpoint to be used on the Lustre MDT and OST filesystems while they are mounted and in use subject to any limitations of the original ioctl() commands themselves.
