Hi all,

this series against the VFS vfs.super branch finishes off the work to remove
get_super and move (almost) all upcalls to use the holder ops.

The first part is the missing btrfs bits so that all file systems use the
super_block as holder.

The second part is various block driver cleanups so that we use proper
interfaces instead of raw calls to __invalidate_device and fsync_bdev.

The last part than replaces __invalidate_device and fsync_bdev with upcalls
to the file system through the holder ops, and finally removes get_super.

It leaves user_get_super and get_active_super around.  The former is not
used for upcalls in the traditional sense, but for legacy UAPI that for
some weird reason take a dev_t argument (ustat) or a block device path
(quotactl).  get_active_super is only used for calling into the file system
on freeze and should get a similar treatment, but given that Darrick has
changes to that code queued up already this will be handled in the next
merge window.

A git tree is available here:

    git://git.infradead.org/users/hch/misc.git remove-get_super

FYI, I've added patches 2-5 as a topic branch to btrfs for-next.

Hum, I don't see them there. Some glitch somewhere?

There will be a delay before the patches show up in the pushed for-next
branch, some tests failed (maybe not related to this series) and there
are other merge conflicts that I need to resolve first.
