Sure, will do.  However, my v2 patch makes use of __free() cleanup
functionality, which in turn only applies back to v6.6 stable kernels.

I guess i shall make another version of the patch that is suitable only for v5.4
to v6.1 stable releases, right?  How shall i format the patch so that it targets
only these old versions?


cheers,
Petko
