[PATCH] SELinux: Add security hook definition for getioprio and insert hooks
Add a new security hook definition for the sys_ioprio_get operation. At
present, the SELinux hook function implementation for this hook is
identical to the getscheduler implementation but a separate hook is
introduced to allow this check to be specialized in the future if
necessary.
This patch also creates a helper function get_task_ioprio which handles the
access check in addition to retrieving the ioprio value for the task.
