Description

Running parallel e2fsck ("-m 32") does not show a proper summary of the total inodes in the filesystem at the end. For example, it shows that a large number of inodes are processed (545M inodes in total), but the summary only shows 370k inodes, which isn't even the total processed by a single thread in pass1:
