Thanks for the kind suggestion. Here is single statement, I've checked
coding-style in Documentation. It's no necessary to use brace for this.
And checkpatch didn't report anything.

Also, I found some reference at
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/mm/vmscan.c?h=v5.13#n3066

But anyway, I could update it when applying, either looks good to me.

Thanks,
