The nvdimm block driver abuse revalidate_disk in a strange way, and
totally unrelated to what other drivers do. Simplify this by just
calling nvdimm_revalidate_disk (which seems rather misnamed) from the
probe routines, as the additional bdev size revalidation is pointless
at this point, and remov
Remove the now unused helper.

Keep control in the NVMe driver instead of going through an indirect
call back into ->revalidate_disk. Also reorder the function a bit to be
easier to follow with the additional code.
And now that we have removed all callers of revalidate_disk() in the nvme
code, ->revalidate_disk is only called
Only virtio_blk and xen-blkfront set the revalidate argument to true,
and both do not implement the ->revalidate_disk method. So switch
to the helper that just updates the size instead.

Hi Jens,
this series removes the revalidate_disk() function, which has been a
really odd duck in the last years. The prime reason why most people
use it is because it propagates a size change from the gendisk to
the block_device structure. But it also calls into the rather ill
defined ->revalida
Replace bd_invalidate with a new BDEV_NEED_PART_SCAN flag in a bd_flags
variable to better describe the condition.

unlock_native_capacity is never called from check_disk_change(), and
while revalidate_disk can be called from it, it can also be called
from two other places at the moment.

revalidate_disk is a relative awkward helper for driver use, as it first
calls an optional driver method and then updates the block device size,
while most callers either don't need the method call at all, or want to
keep state between the caller and the called method.
Add a revalidate_disk_size h
Instead of calling revalidate_disk just do the work directly by
calling sd_revalidate_disk, and revalidate_disk_size where needed.

Linux supports running the RPMsg protocol over the VirtIO transport
protocol, but currently there is only support for VirtIO clients and
no support for a VirtIO server. This patch adds a vhost-based RPMsg

Why net-next though? It's a bugfix, can go into net.
