Add a description of the "ignore" pseudo mount option that can be used
to provide a generic indicator to applications that the mount entry
should be ignored when displaying mount information.

A "strictexpire" mount option has been added to the autofs file system.

It is meant to be used in cases where a GUI continually accesses or an
application frquently scans an automount directory tree causing an
accumulation of otherwise unused mounts.

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.

Fixes: ac6424b9 ("sched/wait: Rename wait_queue_t => wait_queue_entry_t")
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Rename:

	wait_queue_t		=>	wait_queue_entry_t

'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.

Start sorting this out by renaming it to 'wait_queue_entry_t'.

This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',
which is the more canonical nomenclature for such data types.

This documents autofs from the perspective of what the module actually
supports rather than how automount is expected to use it.

It is formatted using "markdown" and works best with Markdown.pl
(markdown_py doesn't like some constructs).
