Subject: [PATCH 169/436] drivers/net: vortex fix locking issues
|
|
|
|
Argh, cut and paste wasn't enough...
|
|
|
|
Use this patch instead. It needs an irq disable. But, believe it or not,
|
|
on SMP this is actually better. If the irq is shared (as it is in Mark's
|
|
case), we don't stop the irq of other devices from being handled on
|
|
another CPU (unfortunately for Mark, he pinned all interrupts to one CPU).
