Ok, fair enough. The context it was written in was that callers should not
need to know the internals of what mark_page_accessed does. Initially I
thought there might be filesystem users that really should not know the
internals but that is not necessary obviously. I still feel that
init_page_accessed shows the intent more clearly and you're certainly
right that the checking PageReferenced is redundant. I don't object to
the patch but I don't think it's obviously better either other than it
avoids the temptation of anyone using __SetPageReferenced incorrectly.
