GR context associated with channel is updated in various driver paths. Sequence to do the same is disable the TSG, preempt the TSG, update the GR context or instance block and then enable the TSG. These operations and runlist updates for channel have to be done under TSG specific ctx_init_lock to avoid the race. suspend_contexts and resume_contexts needs special handling which is not covered in this patch.
