Thanks, that helps me not duplicate anything. One of the first ones I
was looking at (before your post) was viotape.c, which is in your patch
set. However, looking at the uses of the semaphore, I see that on line
409-410 the following code:
if (noblock)
return count;
which seems to ignore the fact that the semaphore has been downed (not
to mention the dma buffer and op struct allocations. I think it should be:
if (noblock)
ret = count;
goto free_dma;
instead. Do you want to make sure I'm right about that and fold it into
your patch? Or have you already submitted your patch (or should it be
in a separate patch? Alternatively, I can submit the patch if you don't
want to bother with it.
