As he says, the patch is rather ugly and doesn't really address the
root problem.  But if it works for you, that is good.

I think that the "right" approach is to claim reconfig_sem (which is
currently unused I think) while writing out the superblocks, and when
releasing the per-device superblock, and probably when doing a few
other things.

I will have a closer look over the code and see how well this can
work.

Thanks,
