Sebastian Ott b4563e891a [S390] cio: wait for channel report ... To fetch a pending channel report word (crw) we use a kernel thread which triggers stcrw and sleeps on a semaphore. The s390 machine check handler uses crw_handle_channel_report to handle one crw if needed. This patch replaces the semaphore with a waitqueue (to block the kernel thread) and an atomic_t (to count the number of pending requests). By this we achieve the ability to force this thread to check for a pending crw (independent on when it is triggered by the machine check handler) and wait for this action to finish.
