I use the upstream kernel (3.2-rc2) and uptodate e2fsprogs master branch code, the error report will emerge after my steps above. My /dev/sda is small (about 100G), so I guess: # create /test/1 ~ /test/100 (e_len == 2) # make /test/5 's e_len to 1024 may replicate this problem on larger disk. -- -- Best Regard Robin Dong -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
