  "message": "rmap: remove anon_vma check in page_address_in_vma()\n\nCurrently page_address_in_vma() compares vma-\u003eanon_vma and\npage_anon_vma(page) for parameter check, but in 2.6.34 a vma can have\nmultiple anon_vmas with anon_vma_chain, so current check does not work.\n(For anonymous page shared by multiple processes, some verified (page,vma)\npairs return -EFAULT wrongly.)\n\nWe can go to checking all anon_vmas in the \"same_vma\" chain, but it needs\nto meet lock requirement.  Instead, we can remove anon_vma check safely\nbecause page_address_in_vma() assumes that page and vma are already\nchecked to belong to the identical process.\n\nSigned-off-by: Naoya Horiguchi \u003cn-horiguchi@ah.jp.nec.com\u003e\nReviewed-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
