2020-05-07vboxsf: don't use the source name in the bdi nameChristoph Hellwig
Simplify the bdi name to mirror what we are doing elsewhere, and drop them name in favor of just using a number. This avoids a potentially very long bdi name. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2020-02-08fs: Add VirtualBox guest shared folder (vboxsf) supportHans de Goede
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.
