Hi,

I have applied 1, 2 and 3 from this series into:
https://github.com/luisbg/linux-befs/tree/befs-next

I had already tested and acked the 3 commits above. Having them in the above git
branch [0] makes it easier to see the order of all recent commits.

Andrew,
I hope this process works for you. If not, let me know and I can adapt to however
you prefer it to be.

Thanks Salah :)

Luis
