Subject: [PATCH] arch/i386/kernel/irq.c: do_IRQ()
Date: Mon, 20 May 2002 17:05:23 -0700 [thread overview]
Message-ID: <20020520170523.I20837@ayrnetworks.com> (raw)
Though a comment in arch/i386/kernel/irq.c: do_IRQ() clearly states:
* 0 return value means that this irq is already being
* handled by some other CPU. (or is disabled)
it seems that the function can only ever return (1). We wrote some low-level
interrupt handling code that depends on the correct value of this function.
Is the following patch what was initially desired? (patched against 2.4.18
tarball from kernel.org...)
Thanks,
William Jhun
