Bisect didn't work. There is a regression between 4.17 and 4.18-rc4 on ext4fs that causes it fail to mount a file system:
There are ways to deal with that, e.g.:
* Manually apply the fix for the ext4 regression when necessary * Run "git bisect skip" for commits which aren't testable * Manually find another commit which can be tested
