Subject: HWPOISON: return 0 to indicate success reliably
X-Git-Tag: v2.6.33-rc1~45^2~18
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=138ce286eb6ee6d39ca4fb50516e93adaf6b605f;p=pandora-kernel.git

HWPOISON: return 0 to indicate success reliably

Return 0 to indicate success, when
- action result is RECOVERED or DELAYED
- no extra page reference

Note that dirty swapcache pages are kept in swapcache, so can have one
more reference count.
