Subject: [PATCH] mm: Ensure that pfn_valid is called once per pageblock when reserving pageblocks
Date: Thu, 1 Dec 2011 11:29:04 +0100 [thread overview]
Message-ID: <20111201102904.GA8809@tiehlicka.suse.cz> (raw)
Hi,
the patch bellow fixes a crash during boot (when we set up reserved
page blocks) if zone start_pfn is not block aligned. The issue has
been introduced in 3.0-rc1 by 6d3163ce: mm: check if any page in a
pageblock is reserved before marking it MIGRATE_RESERVE.
I think this is 3.2 and stable material.
