 Description   

It would be very useful to enable multi-threaded e2fsck for all test runs by default. This would be best handled by adding an option in /etc/e2fsck.conf so that the default behavior can easily be changed without having to modify the code.

Comment by Andreas Dilger [ 26/Nov/21 ]

e2fsck has been running in parallel mode for testing since commit v2_13_56-9-g55a4357424.

What remains to be done here is to enable parallel checking by default for all e2fsck runs.
