Name	Describe
add_wait_queue
prepare_to_wait	Note: we use "set_current_state()" _after_ the wait-queue add,* because we need a memory barrier there on SMP, so that any* wake-function that tests for the wait-queue being active* will be guaranteed to see waitqueue addition _or_ subsequent
prepare_to_wait_event
blk_mq_mark_tag_wait	Mark us waiting for a tag. For shared tags, this involves hooking us into* the tag wakeups. For non-shared tags, we can simply mark us needing a* restart. For both cases, take care to check the condition again after* marking us as waiting.
pin_kill
eventfd_read
eventfd_write
handle_userfault	The locking rules involved in returning VM_FAULT_RETRY depending on* FAULT_FLAG_ALLOW_RETRY, FAULT_FLAG_RETRY_NOWAIT and* FAULT_FLAG_KILLABLE are not straightforward
userfaultfd_event_wait_completion
userfaultfd_ctx_read
__add_wait_queue_exclusive	Used for wake-one threads:
