1ece2c43b8 vboxsf: explicitly deny setlease attempts 
vboxsf does not break leases on its own, so it can't properly handle the
case where the hypervisor changes the data. Don't allow file leases on
vboxsf.

4b4db9b4c7 vboxsf: Convert vboxsf to read_folio 
This is a "weak" conversion which converts straight back to using pages.
A full conversion should be performed at some point, hopefully by
someone familiar with the filesystem.

187c82cb03 fs: Convert trivial uses of __set_page_dirty_nobuffers to filemap_dirty_folio 
These filesystems use __set_page_dirty_nobuffers() either directly or
with a very thin wrapper; convert them en masse.

2 new helper functions.

This is a preparation patch for adding atomic_open support.

0fd1695766 fs: Add VirtualBox guest shared folder (vboxsf) support 
VirtualBox hosts can share folders with guests, this commit adds a
VFS driver implementing the Linux-guest side of this, allowing folders
exported by the host to be mounted under Linux.

This driver depends on the guest <-> host IPC functions exported by
the vboxguest driver.
