Comment 3 for bug 1829563

Tests with xfstests
===================

The xfstests test suite has been run on the original
and modified kernels -- on all cache modes available
(writethrough, writeback, writearound, none).

Summary: no regressions observed; apparently one FIX
achieved in the writearound cache mode (generic/371).

(attached script: 'test-bcache-cache-modes.sh')

Details:
-------

The bcache device is made of
- caching device: 1 GB partition in NVMe drive
- backing device: 5 GB partition in SCSI disk

The comparison of the output of xfstests/check script
for the 'Failures' with original (orig) and modified
(test) test kernels is provided below.
