It's doable, but I think it's a bit too much only to solve this problem. The alternative, which is what I had in mind, was to forward-port this change to mainline when local_locks gets merged upstream. But I guess this will only happen when sleeping spinlocks are merged? -- 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
