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?
