Subject: [PATCH 44/52] tests: Add broken files for all broken tests |
|
|
|
Each broken file contains the rough frequency of brokeness as well |
|
as a brief explanation of what happens when it breaks. Estimates |
|
of failure rates are not statistically significant and can vary |
|
run to run. |
|
|
|
This is really just a view from my window. Tests were done on a |
|
small VM with the default loop devices, not real hardware. We've |
|
seen different kernel configurations can cause bugs to appear as well |
|
(ie. different block schedulers). It may also be that different race |
|
conditions will be seen on machines with different performance |
|
characteristics. |
|
|
|
These annotations were done with the kernel currently in md/md-next: |
|
