Subject: ext4 lock ordering patch

  Hi Mingming,

  I've noticed you removed the patch reversing locking order of page lock
and transaction start from ext4 patch queue. Was this because of that
reported performance problem or for some other reason? As far as I've
understood that problem has been just in the patch fixing the delalloc mode
part so just removing that patch would be enough AFAICT.
  Anyway, the problem is I have now ordered mode rewrite for JBD2/ext4
which depends on this patch so the question is how to proceed... Should we
first fix that delalloc problem (are you looking into that?) or do we merge
all the changes and then fixup the delalloc code?
