I've uploaded a fixed package, it's now going to proceed via the normal SRU process.

Add detection of the kernel module version and use an approximation to the zfs 0.8.0 progress and rate reporting for newer kernels. For 0.7.5 we can pass the larger 8.x port_scan_stat_t to 0.7.5 zfs w/o problems and ignore these new fields and continue to use the 0.7.5 rate calculations. == Test == Install the HWE kernel on Bionic, create some large ZFS pools and populate with a lot of data. Issue: sudo zpool scrub poolname and then look at the progress using sudo zpool status Without the fix, the progress stats are incorrect. With the fix the duration and rate stats as a fairly good approximation of the progress. Since the newer 0.8.x zfs does scanning now in two phases the older zfs tools will only report accurate stats for phase #2 of the scan to keep it roughly compatible with the 0.7.x zfs utils output. == Regression Potential == This is a userspace reporting fix so the zpool status output is only affected by this fix when doing a scrub, so the impact of this fix is very small and limited. ------------------------------------ I ran a zpool scrub prior to upgrading my 18.04 to the latest HWE kernel (5.3.0-26-generic #28~18.04.1-Ubuntu) and it ran properly: eric@eric-8700K:~$ zpool status pool: storagepool1 state: ONLINE scan: scrub repaired 1M in 4h21m with 0 errors on Fri Jan 17 07:01:24 2020 config: NAME STATE READ WRITE CKSUM storagepool1 ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 ata-WDC_WD20EZRZ-00Z5HB0_WD-WCC4M3YFRVJ3 ONLINE 0 0 0 ata-ST2000DM001-1CH164_Z1E285A4 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 ata-WDC_WD20EZRZ-00Z5HB0_WD-WCC4M1DSASHD ONLINE 0 0 0 ata-ST2000DM006-2DM164_Z4ZA3ENE ONLINE 0 0 0 I ran zpool scrub after upgrading the kernel and rebooting, and now it fails to work properly.
