Poul-Henning Kamp 2e27173fb5 Add a D_NOGIANT flag which can be set in a struct cdevsw to indicate ... that a particular device driver is not Giant-challenged. SPECFS will DROP_GIANT() ... PICKUP_GIANT() around calls to the driver in question. Notice that the interrupt path is not affected by this! This does _NOT_ work for drivers accessed through cdevsw->d_strategy() ie drivers for disk(-like), some tapes, maybe others.		2002-09-27 19:47:59 +00:00
