[PATCH] [UBI] [1/3] ubi notifications API

[Artem Bityutskiy]

Dmitry,

I've re-work the first patch of yours. I think the locking should
be correct now. The commit message shortly list the changes I've
done.

I also send the second patch. The only thing I fixed there was
the spelling of your name - I made it start with a capital letter.
I hope you do not mind.

Please, provide the third patch. You should not try to open an
UBI volume from within a notifier, because it won't work. I
think you simply did not test your patches before sending.
Neither did I. But please, this time, do test the patches.
It is very easy to do with nansim.

I'll send the patches as 2 follow-up e-mail for your review.
