Commitac6424b981("sched/wait: Rename wait_queue_t => wait_queue_entry_t") had scripted the renaming incorrectly, and didn't actually check that the 'wait_queue_t' was a full token. As a result, it also triggered on 'wait_queue_token', and renamed that to 'wait_queue_entry_token' entry in the autofs4 packet structure definition too. That was entirely incorrect, and not intended. The end result built fine when building just the kernel - because everything had been renamed consistently there - but caused problems in user space because the "struct autofs_packet_missing" type is exported as part of the uapi. This scripts it all back again: git grep -lw wait_queue_entry_token | xargs sed -i 's/wait_queue_entry_token/wait_queue_token/g' and checks the end result.
