This commit ac6424b981bce1c4bc55675c6ce11bfe1bbfa64f ("sched/wait:
Rename wait_queue_t => wait_queue_entry_t") ends up renaming the
autofs_packet_missing, autofs_packet_expire_multi and autofs_v5_packet
member previously named wait_queue_entry to wait_queue_entry_token. Was
it intentional to force an user space build breakage when building
against v4.13-rc headers for autofs headers?

Thanks
