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));
The Solaris Porting Layer (SPL) is a Linux kernel module which provides many of the Solaris kernel APIs. This shim layer makes it possible to run Solaris kernel code in the Linux kernel with relatively minimal modification. This can be particularly useful when you want to track upstream Solaris development closely and don’t want the overhead of maintaining a large patch which converts Solaris primitives to Linux primitives.
Documentation for building, configuring, and using the SPL can be found at: http://wiki.github.com/behlendorf/spl/
