Nothing here is a problem in and of itself.  The repeated polls are a
workaround for the usual race when waiting on a poll/select and a
signal.  (There are better ways to deal with this, and I'd happily take
a patch.)

So, what's the real problem that prompted you to look at this?  Is mount
failing?
