Why the resend?

Nothing happens until the merge window closes with the release of -rc1
(almost certainly on this coming Sunday).  I goofed and did not act on
this faster, and so it is my fault this did not make it into linux-next
before the merge window.  But I am not going to rush this forward.

You also ignored my review and have not even descibed why it is safe
to change the type of a filesystem parameter.

-	fsparam_u32("hidepid",	Opt_hidepid),
+	fsparam_string("hidepid",	Opt_hidepid),

Especially in light of people using fsconfig(fd, FSCONFIG_SET_...);

All I need is someone to point out that fsparam_u32 does not use

My apologies for being grumpy but this feels like you are asking me to
go faster when it is totally inappropriate to do so, while busily
ignoring my feedback.

I think this should happen.  But I can't do anything until after -rc1.
