Subject: [PATCH 44/83] tests: Add broken files for all broken tests
|
|
|
25786b |
|
|
|
25786b |
Each broken file contains the rough frequency of brokeness as well
|
|
|
25786b |
as a brief explanation of what happens when it breaks. Estimates
|
|
|
25786b |
of failure rates are not statistically significant and can vary
|
|
|
25786b |
run to run.
|
|
|
25786b |
|
|
|
25786b |
This is really just a view from my window. Tests were done on a
|
|
|
25786b |
small VM with the default loop devices, not real hardware. We've
|
|
|
25786b |
seen different kernel configurations can cause bugs to appear as well
|
|
|
25786b |
(ie. different block schedulers). It may also be that different race
|
|
|
25786b |
conditions will be seen on machines with different performance
|
|
|
25786b |
characteristics.
|
|
|
25786b |
|
|
|
25786b |
These annotations were done with the kernel currently in md/md-next:
|
|
|
25786b |
|
|
|
25786b |
facef3b96c5b ("md: Notify sysfs sync_completed in md_reap_sync_thread()")
