 This week I ran into fs corruption on wapbl on a raid1 on a pair of
 SATA SSDs, with a current kernel from 2019-11-14 that included
 Circumstances are confusing and there were no operational symptoms
 until the nightly find / tripped on a corrupted directory entry, so it
 might not be in any way related; but I figured I'd mention it.
 Regardless of that, it also is kinda weird that DIAGNOSTIC would
 affect the problem.
