setting task->ioprio from a kernel thread

In OCFS2 there is currently an in-kernel heartbeat thread that really
wants to communicate liveness to other nodes as quickly as possible by
writing to a block device. Setting aside the specific wisdom of a
kernel heartbeat thread for a bit, has it been considered that kernel
threads might want to set their io priority with the task->ioprio bits?
Neither set_task_ioprio() nor sys_ioprio_set() seem to be accessible
to modules and open-coding it is clearly a bad idea. Would the universe
be opposed to a _GPL() export of, say, the sys_() interface?
