There were many. You can read about what was done here: https://lwn.net/Articles/484932/ The original is here: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ccd49c2391773ffbf52bb80d75c4a92b16972517 But more were added. But that is back in 3.3, so 3.10 has all the required updates. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
