Subject: [-mm][splitlru][PATCH 0/3] munlock rework
Date: Sat, 19 Jul 2008 17:42:13 +0900	[thread overview]
Message-ID: <20080719084213.588795788@jp.fujitsu.com> (raw)

-- 

old munlock processing of unevictable-lru use pagewalk.
because get_user_pages() can't grab PROT_NONE page.

then, current -mm has two problem.
  - build error on nommu machine
  - runtime error on HIGHPTE machine.

So, I hope rework below concept

	Old implementation
	   - use pagewalk

	New implementation
	   - use __get_user_pages()


I tested this patch on
  IA64:                 >24H stress workload
  x86_64:               ditto
  x86_32 with HIGHPTE:  only half hour



Li-san, Could you please try to this patch on your 32bit machine?
