Acmcl2.516 net.unix-wizards utcsrgv!utzoo!decvax!duke!chico!harpo!floyd!cmcl2!salkind Thu Feb 18 17:34:19 1982 Just curious - bio.c query In both physio() and swap(), the test if (bp->b_flags&B_WANTED) wakeup((caddr_t)bp); runs at spl6(). Why does it have to run at spl6()? In brelse() and iodone() the same test does not run at spl6().
