Have you glanced at the committed code? the all_cpus stuff can actually be used by any code, not just the mbuf code. Everything else this delta includes are really mbuf subsystem-specific changes, which cannot be exported. What would be neat now is if someone took it upon themselves to actually implement the callback hooks so that any subsystem can use them. > thanks, > -- > -Alfred Perlstein [alfred@freebsd.org] > Ok, who wrote this damn function called '??'? > And why do my programs keep crashing in it? -- Bosko Milekic bmilekic@technokratis.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
