Yes, I copied fs/aufs25. See attached patch which fixes this warning and
also fixes some crashes, I will post new crash report pretty soon :)
Thanks for the patch.
It is a problem of unmatching the function signature. In my local
version, I already throw the marco MmTree away.
But I don't think this unmatching is the one and only cause of your
problem. I am afraid your last stack trace shows another problem.
Yes there is another problem... Worst thing is that it crashes in
different places... but sometimes it works without problems with the
same mount command :)
See attacment
