Hi, I was just wanted to send a message to janitors - We've identified a set of busy loops, waiting on hardware in the Linux kernel. These are perhaps not the best way to wait for a device to become ready and can occasionally freeze the system. These need to be fixed by adding timeouts (for example by using rdtscll to wait for 2 clock cycles). The list is here => http://pages.cs.wisc.edu/~kadav/busy_waits.txt I have added some caveats to be on the safe side. I will also add/update this list as time passes by and as these are fixed (or as I identify more). Thanks, Asim -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
