I think it doesn't have to initialize function callback function which is
member of pdflush_work discripter twice and It should do that in head of in
infinity loop before calling schedule(). Because the latter initialization
which is executed at the 143th line of the mm/pdflush.c has done in order to be
reused. And I think if it initialize that in the head of loop, the former which
is initialized at the 96th line can omit doing that.
