Why not just make UMA the userland implementation, too? It should only cost us one kernel trap instruction per allocation/deallocation operation. With fine-grained kernel locking, why we wouldn't want to trust the same code to both tasks, and possibly optimize more because it can do that? -- Brian Fundakowski Feldman \'[ FreeBSD ]''''''''''\ <> [EMAIL PROTECTED] \ The Power to Serve! \ Opinions expressed are my own. \,,,,,,,,,,,,,,,,,,,,,,\ _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
