There are 12 questions tagged as loop:
A loop device allows any file to be mounted as a filesystem image. Not to be confused with a loopback interface in networking.
From those
I bring this in attention of moderators as I find the current situation confusing.
As my personal point of view, the loop tag should remain as is for the 4 loop device questions and the 8 control flow questions should loose their loop tags.
I don't remember for sure, but I suspect the choice to have loop mean loop devices rather than control flow is due to programming being mostly off-topic on this site. Loop constructs in shells do come up from time to time, and it's natural to use the loop tag in this sense.
Given the wide mismatch between documented meaning and actual use, I've retagged the loop device questions to loop-device and copied over the tag wiki.
It remains to be seen what to do with loop: should it be a synonym of control-flow? Or should it be blacklisted? Note that in addition to being a natural choice for the (rare) questions about loop constructs, it is likely to come up in migrations from Stack Overflow.
for and while related questions, then would be logic (and politically correct) to also have conditional tag for if and case related questions.

As you pointed out, loop's tag wiki is about loopback devices, so I left those 4 and retagged the other 8 to control-flow. It might be a good idea to change the remaining loop questions to something like loop-devices to avoid future confusion, but I left it for the moment (anyone with 500 rep is welcome to retag them)
