The CPU hotplug callback related to writeback calls writeback_set_ratelimit()
during every state change in the hotplug sequence. This is unnecessary
since num_online_cpus() changes only once during the entire hotplug operation.
So invoke the function only once per hotplug, thereby avoiding the
unnecessary repetition of those costly calculations.

Looks good to me. I'll include it in the writeback tree.
Hi Fengguang,
Could you tell me when inode->i_state & I_DIRTY will be set? thanks.

Thanks,
