Once I saw how orthogonal io_uring was to "regular" process trees, I figured this series didn't need seccomp input. (I mean, I am still concerned about attack surface reduction, but that seems like a hard problem given io_uring's design -- it is, however, totally covered by the LSMs, so I'm satisfied from that perspective.) I'll go review... thanks for the poke. :) -- Kees Cook
