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.
