Kernel log message about loop0 capacity change

Whenever I am using the TrueNAS GUI, I see this log message periodically; it seems to be associated with browsing different sections of the GUI, or refreshing and logging in.

Here is an example, with the blocks of time corresponding to periods I was using the TrueNAS GUI.

SCALE, Community Edition, 25.04.2.5 but it was happening on 25.04.2.4 as well.

I don’t seem to be having any issues it just seems strange, was not happening for the first few weeks since I set up this NAS, and adds noise to the log messages.

Suggestions for where to poke?
