Renaming makes backports more complicated, because stable teams will
have to 'undo' name changes.
Stable teams are already overwhelmed by the amount of backports, and
silly merge conflicts.

Take another example :

u64 timecounter_read(struct timecounter *tc)

You would think this function would read the timecounter, right ?

Well, it _updates_ many fields from @tc, so a 'better name' would also
be useful.

linux kernel is not for casual readers.
