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

Change description:
â
This data race was found by our concurrency fuzzer.

Thus use the spin lock âmp->log->gclockâ for the assignment of
the data structure member âlog->cflagâ to a local variable
in this function implementation.


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