I suspect all sane people are already on xmas break, which explains why people are being quiet. They _should_ be. But since I'm not in that sane group, I decided to just bypass the normal channels and apply it directly. It really isn't all that critical, since I don't expect anybody to actually disable the posix timer subsystem: I think the config variable came out of the kernel minimization project, and it's probably much more likely that people turn off CFI (particularly since you afaik still need to build with clang to get it) than that they'd turn off the posix timer support. But I think it's a worthy cleanup of some messy system call macros, so I wanted to put this behind us whether it truly matters or not. Linus
