kernel/sched: Add missing SMP thread abort case (d4429276) · Commits · Wenxi XU / zephyr

The loop in thread abort on SMP where we wait for the results on an IPI correctly handled the case where a thread running on another CPU gets its interrupt and self-aborts, but it missed the case where the other thread pends before receiving the interrupt. Signed-off-by:
