Nicholas Bellinger fd594155e4 scsi: sched/wait: Add wait_event_lock_irq_timeout for TASK_UNINTERRUPTIBLE usage ... commit 25ab0bc334 upstream. Short of reverting commit 00d909a107 ("scsi: target: Make the session shutdown code also wait for commands that are being aborted") for v4.19, target-core needs a wait_event_t macro can be executed using TASK_UNINTERRUPTIBLE to function correctly with existing fabric drivers that expect to run with signals pending during session shutdown and active se_cmd I/O quiesce. The most notable is iscsi-target/iser-target, while ibmvscsi_tgt invokes session shutdown logic from userspace via configfs attribute that could also potentially have signals pending. So go ahead and introduce wait_event_lock_irq_timeout() to achieve this, and update + rename __wait_event_lock_irq_timeout() to make it accept 'state' as a parameter.
