Seems the below stable tagged rtmutex fixes won't go further back than 3.14 unless someone does the leg work of making them applicable. Ergo, this series contains.. 397335f0 rtmutex: Fix deadlock detector for real 82084984 rtmutex: Detect changes in the pi lock chain 3d5c9340 rtmutex: Handle deadlock detection smarter 27e35715 rtmutex: Plug slow unlock race With.. 0c106173 rtmutex: Document rt_mutex_adjust_prio_chain() ..applied prior, the series can be applied at least as far back as 3.0 should anyone desire to do so. I tested by applying them to 3.12-stable, merge 3.12-rt, beat the result enthusiastically, switch to 3.0-stable, repeat. Both ends appear fine, so in between should be fine as well should Thomas ack them. -Mike -- 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
