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
