based frontends. Currently the frontends which implement
similar code for sharing big buffers between frontend and
backend are para-virtualized DRM and sound drivers.
Both define the same way to share grant references of a
data buffer with the corresponding backend with little
differences.

Move shared code into a helper module, so there is a single
implementation of the same functionality for all.

In general I'm fine with this approach.

With the concerns raised for one of the other patches I wanted to wait
for V2 of the series.
Ah, I waited for any comments before rolling v2 out ;)
Or won't the resulting change require a
modification of this patch?

This patch won't change, it is only DRM related

The concern for the DRM patch is already resolved

and the corresponding patch is on review now [1]


It would be nice if you could point out in the commit message whether
you are doing code movement (with some renames) only, or if there are
any functional changes involved (and which ones).
Sure, this is pure code movement, no functional changes
This would make the
review much easier and less time consuming.
