1. Set the default process state to TASK_UNINTERRUPTIBLE during sleep. This change is made because our current code does not check whether a process was interrupted by a signal. 2. Prefix all SCST wait_event-related macros with 'scst_'. This helps to distinguish SCST-specific macros from those provided by the Linux kernel itself. 3. Add the capability to return an error code when a process in a non-TASK_UNINTERRUPTIBLE state is interrupted by a signal. 4. Divide the wait_event_locked function based on each lock type, resulting in the following new functions: scst_wait_event_lock(), scst_wait_event_lock_bh(), and scst_wait_event_lock_irq().
