It is also about the length of name. To me now a days CFQ code looks
pretty messy with very long names or lines at many a places.
So yes, "cfqd->serving_wl_class" and "cfqd->serving_wl_type" is more
readable than "cfqd->wl_class" and "cfqd->wl_type". But it also
increases the string length significantly.
I don't know. Some of the strings seem too long and code spills into
multiple lines for a single statement.
Anyway, for this I guess I will retain "serving" keyword.
Thanks
Vivek
