do_anonymous_page's pte_wrprotect causes some confusion: in such a case,
vm_page_prot must already be forcing COW, so must omit write permission, and
so the pte_wrprotect is redundant.  Replace it by a comment to that effect,

[PATCH] shrink_list(): skip anon pages if not may_swap

Martin Hicks' page cache reclaim patch added the 'may_swap' flag to the
scan_control struct; and modified shrink_list() not to add anon pages to
the swap cache if may_swap is not asserted.

Ref:  http://marc.theaimsgroup.com/?l=linux-mm&m=111461480725322&w=4

However, further down, if the page is mapped, shrink_list() calls
try_to_unmap() which will call try_to_unmap_one() via try_to_unmap_anon ().
 try_to_unmap_one() will BUG_ON() an anon page that is NOT in the swap
cache.  Martin says he never encountered this path in his testing, but
agrees that it might happen.

This patch modifies shrink_list() to skip anon pages that are not already

[PATCH] swaptoken tuning

It turns out that the original swap token implementation, by Song Jiang, only
enforced the swap token while the task holding the token is handling a page
fault.  This patch approximates that, without adding an additional flag to the
mm_struct, by checking whether the mm->mmap_sem is held for reading, like the
page fault code does.

This patch has the effect of automatically, and gradually, disabling the
enforcement of the swap token when there is little or no paging going on, and
"turning up" the intensity of the swap token code the more the task holding
the token is thrashing.

Thanks to Song Jiang for pointing out this aspect of the token based thrashing
control concept.

The new code shows a slight degradation over the old swap token code, but
still a big win over running without the swap token.
