From: chas williams <chas@cmf.nrl.navy.mil> Date: Sun, 01 Jun 2003 14:57:02 -0400 but on a single processor machine (i.e. #undef CONFIG_SMP) there is no chance that there will be reads/writes from other processors so i dont need any locking OR protection from interrupts. Either you need to pretect a code sequence from an IRQ context execution while holding the lock or you don't. :-) Really, all your macros just make the driver that much less portable. And I don't see what you'll gain by having interrupts enabled for such short sequences of code on uniprocessor. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
