Do not allocate MJUM9BYTES clusters under any circumstances. Trying to allocate them when the system is under memory pressure is enormously expensive and stands a good chance of livelocking the system if you try to allocate too many too quickly, even when allocating with M_NOWAIT.
Honestly, support for clusters > PAGE_SIZE should probably be retired from the kernel given the significant havoc they cause. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
