However, that depends on the interfaces being used. Sure, when a twit "moves things to userland" by marshalling stuff through sysfs, the only thing it achieves is more sysfs crap *and* more internal kernel APIs being cast in stone. However, when the code really is a series of normal syscalls (on the level of "all we call is sys_something()"), it makes a lot of sense to take the damn thing to userland and leave it there... - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
