When I tried this in 3.14.x the kernel would lock up immediately during boot (not even a console). This may or may not have to do with me also using the BFS scheduler, but it's IMHO something that should be double-checked. I also tried to backport the necessary macros but that went nowhere fast, since they ended up pulling in most of the rcu-task stuff.. -h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
