Priority Inheritance?Priority Inheritance?Posted Jul 20, 2006 0:09 UTC (Thu) by mingo (subscriber, #31122)In reply to: Priority Inheritance? by corbet Parent article: Kernel Summit 2006: Realtime
yes. The kernel/rtmutex.c code which implements user-space PI (the new PI-futexes API) is the exact same code used for preemptible spinlocks too in -rt. It was not entirely trivial to merge the two uses into the same subsystem, but it's reality now. (And i dont want to take all credit for it, large portions of this solution were designed and written by Thomas Gleixner, Esben Nielsen and Steven Rostedt.)
