    Fix up over-eager 'wait_queue_t' renaming · 7cee9384
    Linus Torvalds authored
    Commit ac6424b9 ("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.
