    Description

      New upstream kernels added additional checking to CONFIG_DEBUG_ATOMIC__SLEEP to ensure no blocking calls are made while in not RUNNIG state,as otherwise the state could be lost.

      For us offenders are in __l_wait_event for callbacks,
      in libcfs_debug_dumplog and in libcfs_sock_accept
