How do you think about a wording variant like the following?

Change description:
A data race can occur for the data structure member âflagâ.
This data race was found by our concurrency fuzzer.

Thus use the spin lock âgclockâ for the resetting of five
data structure members in this function implementation.


Would you like to add the tag âFixesâ to the commit message?
