At the top of Grow_restart (in Grow.c), just put
return 0;
That will definitely get you your array back.
I think the correct fix will be to put:
if (info->reshape_progress > SOME_NUMBER)
return 0;
at the top of Grow_restart. I just have to review exactly how it
works to make sure I pick the correct "SOME_NUMBER".
Also
if (__le64_to_cpu(bsb.length) <
info->reshape_progress)
continue; /* No new data here */
might need to become
if (__le64_to_cpu(bsb.length) <
info->reshape_progress)
return 0; /* No new data here */
but I need to think carefully about that too.
