fasync: Fix placement of FASYNC flag comment
In commit f7347ce4ee7c ("fasync: re-organize fasync entry insertion to allow it under a spinlock") Arnd took an earlier patch of mine that had the comment about the FASYNC flag above the wrong function. When the fasync_add_entry() function was split to introduce the new fasync_insert_entry() helper function, the code that actually cares about the FASYNC bit moved to that new helper. So just move the comment to the right point. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
