That was my thinking, and I'm not sure what I could put in a comment.
Wouldn't it be some mix of words 'flags', 'memory', 'cgroup' and
'charge'... which is just spelling out the name of the function? 

I mean:

	/* Alloc flags for passing to cgroup socket memory charging */

does not add much value, right?
