Hi Greg, Please pick these two commits: 3f1f33206c16c7b3839d71372bc2ac3f305aa802 95cf59ea72331d0093010543b8951bb43f262cac The first one is a prerequisite and the second one is the bug fix, which fixes a kernel warning when perf cgroup is used. The fix should be applicable to kernels >= 2.6.39 && <= 3.6. I've reproduced the bug and tested the fix in 3.4 stable kernel. -- Li Zefan -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
