Like Eric Dumazet said the idea is good but needs some adjustments.

You might want to see whether a per-cpu work buffer works for this.

It's extremely unfortunately that we can't depend upon the destination
buffer being properly aligned, because we wouldn't need a temporary
scratch area if it were aligned properly.
