Hi Al and Linus,

currently a lot of the file system calls in the early in code (and the
devtmpfs kthread) rely on the implicit set_fs(KERNEL_DS) during boot.
This is one of the few last remaining places we need to deal with to kill
off set_fs entirely, so this series adds new helpers that take kernel
pointers.  These helpers are in init/ and marked __init and thus will
be discarded after bootup.  A few also need to be duplicated in devtmpfs,
though unfortunately.

I see nothing objectionable here.

The only bikeshed comment I have is that I think the "for_init.c" name
is ugly and pointless - I think you could just call it "fs/init.c" and
it's both simpler and more straightforward. It _is_ init code, it's
not "for" init.

Other than that it all looked straightforward to me.
