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
