Is this the latest? It is, mostly. Code committed to the HEAD was slightly modified. Here is the patch as it is in SVN: http://svnweb.freebsd.org/base/head/sys/kern/sched_ule.c?r1=229429&r2=232207&view=patch And today I've fixed one found bug: http://svnweb.freebsd.org/base/head/sys/kern/sched_ule.c?r1=232207&r2=232454&view=patch > Will it apply cleanly on it? > Any "gotchas"? Sorry, I have no idea about difference from 8-STABLE. You may try. -- Alexander Motin
