Probably. I'm going to start looking at what's in 3.18 and start porting changes to 3.14 and earlier. I've only been updating the stable kernels to pull in the mainline stable updates. I haven't reverted anything (unless mainline stable caused things to be obsolete), nor have I added any updates. BTW, I'm going to start with 3.18-rt1 and see what's been added to the other -rt updates. If there's something I need that was added to 3.18-rt1 can you let me know. That is, if it wasn't marked with a stable-rt tag. My scripts will find those. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
