[GIT PULL] vboxsf fixes for 5.14-1

[Hans de Goede]

Hi Linus,

Here is a pull-req with a set of patches fixing a vboxsf bug for 5.14
(I am the vboxsf maintainer).

Linus, sorry for sending this directly through you, instead of going
through some other tree, but trying to get this upstream through the
linux-fsdevel list / patch-review simply is not working.

This bugfix patch-set (3 preparation patches + 1 actual bugfix) fixes
a bug which is actually being hit by users in the wild, e.g. doing
a "git clone" on a vbox guest inside a shared-folder will fail
without his fix. Since you merge pull-req-s for a bunch of other
filesystems directly I'm hoping that you are willing to take this
one too.

This patch-set has been posted on the linux-fsdevel for the first
time on January 21th 2021, so almost 6 months ago and I've send
out several pings and a resend since then, but unfortunately
no-one on the linux-fsdevel list seems to have interest in /
time for reviewing vboxsf patches.

Regards,

Hans
