problem with latest xfsprogs progress code

["James Braid" <jamesb@xxxxxxxxxxxx>]

Running 2.8.18 xfs_repair on a largeish (65TB, ~70M inodes) filesystem on
an x86_64 machine gives the following "progress" output:

12:15:36: process known inodes and inode discovery - 1461632 of 0 inod
es done
12:15:36: Phase 3: elapsed time 14 minutes, 32 seconds - processed 100
571 inodes per minute
12:15:36: Phase 3: 0% done - estimated remaining time 3364 weeks, 3 da
ys, 7 hours, 30 minutes, 45 seconds

Is this a known bug?

Thanks, James
