Proposed fix for oops on SIGINT in splat atomic:64-bit test.
The threads in the splat atomic:64-bit test share the data structure atomic_priv_t ap, which lives on the kernel stack of the splat user-space utility. If splat terminates before the threads, accesses to that memory location by the other threads become invalid. Splat synchronizes with the threads with the call: wait_event_interruptible(ap.ap_waitq, splat_atomic_test1_cond(&ap, i)); Apparently, the SIGINT wakes and terminates splat prematurely, so that GPFs or other bad things happen when the threads subsequently access ap. This commit prevents this by using the uninterruptible form: wait_event(ap.ap_waitq, splat_atomic_test1_cond(&ap, i));
