Hello,
Description: Replace deprecated interruptible_sleep_on_timeout() with direct
wait-queue usage. Also replace some rather odd wait-queue usage with the
existent macros. Also adjusted the wake_up_interruptible() call appropriately,
as I changed all the states to TASK_UNINTERRUPTIBLE (signals were not be checked
in the current code). Patch is compile-tested.
