I don't have perspective on how serious that effort is. But ~2 years
ago DM introduced another consumer of tasklets in dm-crypt, see:
39d42fa96ba1 dm crypt: add flags to optionally bypass kcryptd workqueues

Given that, and other numerous users, is the effort to remove tasklets
valid? What is the alternative to tasklets?
