Summary

jiffies_to_msecs() is expected to return an uint_t. In order to avoid
changing printf format strings, properly cast the result to the
expected type.

What is this macro used for?

Why are you casting forth and back between signed and unsigned?

I think it's self-explaining what the macro has done for ages. You were the last one to touch that line.

I am just casting the result to the expected type, everything else was there already Hans.

I see now how Linux defines this macro / function. Sorry, my bad. I was just looking at the change itself, and wondering what happens to negative time differences ...
