Subject: [PATCH 44/83] 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:
