Subject: [PATCHv2, RFC 05/30] thp, mm: avoid PageUnevictable on active/inactive lru lists
Date: Thu, 14 Mar 2013 19:50:10 +0200 [thread overview]
Message-ID: <1363283435-7666-6-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1363283435-7666-1-git-send-email-kirill.shutemov@linux.intel.com>
From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>
active/inactive lru lists can contain unevicable pages (i.e. ramfs pages
that have been placed on the LRU lists when first allocated), but these
pages must not have PageUnevictable set - otherwise shrink_active_list
goes crazy:

For lru_add_page_tail(), it means we should not set PageUnevictable()
for tail pages unless we're sure that it will go to LRU_UNEVICTABLE.
The tail page will go LRU_UNEVICTABLE if head page is not on LRU or if
it's marked PageUnevictable() too.
