Cover letter [PATCH 0/5] exit: more cleanups/optimizations
Quoted 2 lines · Oleg Nesterov

Plus cleanups + initial (micro)optimizations, more to come.

Yes, exit_notify() needs more changes but I was distracted, will do later.

Until then some more "exit:" changes which also makes sense imo.

Oleg.
