Hi Greg,

Commit 7dac4a1726a9 ("ext4: add validity checks for bitmap block
numbers") seems to be the cause of the regression reported here:

  https://marc.info/?l=linux-ext4&m=152416385122029&w=2

ext4 folks are probably busy at LSF, so no reply yet.  Should this
commit be held until we get word from Ted?

Please excuse broken threading.

Thanks,

                Ilya
