So that's why when I heard of this issue the first time, it was about Redhat/ Fedora Core kernels. But even though this issue is very old, no bug report got through to linux1394-devel until December 2005.
BTW, why not swap the order of expressions: WARN_ON(!(warned++) && in_irq()); \ -- Stefan Richter -=====-=-==- --=- -=-== http://arcgraph.de/sr/ - 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/
