Each broken file contains the rough frequency of brokeness as well

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:

Just to share some results from my side, with 5.19-rc1 (revert my
problematic patch of course), below tests failed.

05r1-bitmapfile failed which is probably because external bitmaps are only
work on ext2 and ext3, I guess other 05*-bitmapfile failed due to the same
reason.
01r5integ /01raid6integ can't finish due to some reason.
BTW, thank you for the effort to make md/mdadm better!
Thanks,
Guoqing
