Description Martin Birgmeier 2021-03-28 13:20:35 UTC 
Scenario:
- FreeBSD main ca. March 13, armv6 running on Raspberry Pi model B+
- Adding network storage using "iscsictl -A -n <name>"
- Swapping to that storage via "swapon /dev/daNpX"
- Inadvertently issuing "iscsictl -R -n <name>"

Result:
- The disk carrying the swap space is removed without warning
- The system deadlocks

Expected result:
- The "iscsictl -R ..." should result in an error message and be refused.
