Subject: [PATCH] BLOCK: Stop fallback_migrate_page() from using page_has_buffers() [try #6]
X-Git-Tag: v2.6.19-rc1~640^2~21
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b398f6bff93a247d2a7099e92905374966e4558f;p=linux-2.6

[PATCH] BLOCK: Stop fallback_migrate_page() from using page_has_buffers() [try #6]

Stop fallback_migrate_page() from using page_has_buffers() since that might not
be available.  Use PagePrivate() instead since that's more general.
