[You were asked to use a reasonable quoting several times. This is
really annoying because it turns the email thread into a complete mess]

I already fix the email client, dont know the reason for quoting.

Not really. You are observing an unexpected behavior of the page reclaim
which hasn't changed for quite some time. So I find more probable that
your non-vanilla kernel is doing something unexpected. It would help if
you could track down how does the unevictable page get down to the
reclaim path. I assume this is a CMA page or something like that but
those shouldn't get to the reclaim path AFIR.

As i said earlier, the kernel i am using is vanilla kernel.
