Revision dd12f48d4e8774415b528d3991ae47c28f26e1ac authored by Bhavesh P. Davda on 17 August 2005, 18:26:33 UTC, committed by Linus Torvalds on 17 August 2005, 19:52:04 UTC
This bug is quite subtle and only happens in a very interesting situation where a real-time threaded process is in the middle of a coredump when someone whacks it with a SIGKILL. However, this deadlock leaves the system pretty hosed and you have to reboot to recover. Not good for real-time priority-preemption applications like our telephony application, with 90+ real-time (SCHED_FIFO and SCHED_RR) processes, many of them multi-threaded, interacting with each other for high volume call processing.
