#5205 is another followup with the logging and a probe through path
capabilities; this allows me to verify that backports are in.
an abfs instance is vulnerable if
```java
fs.hasPathcapability("fs.capability.paths.acls") &&
!fs.hasPathcapability("HADOOP-18546")
```
if that holds, then you need to make sure readahead is disabled/no queue
depth. setting queue depth is the one guaranteed to work everywhere.
