This can't possibly be correct as r254138 just removed this flag. If it isn't obvious how to fix the uses added back in r254141, then r254141 should be reverted instead. Hmm, looking at the relevant bits of r254141, it doesn't look obvious: + /* Detach the old page from the resident tailq. */ + TAILQ_REMOVE(&object->memq, mold, listq); + vm_page_lock(mold); + if (mold->oflags & VPO_BUSY) { + mold->oflags &= ~VPO_BUSY; + vm_page_flash(mold); + } Since nothing is setting this flag, this can't possibly work correctly currently. I wouldn't boot a top-of-tree kernel right now. :( -- John Baldwin _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
