  "message": "[PATCH] Fix crash when ptrace poking hugepage areas\n\nset_page_dirty() will not cope with being handed a page * which is part of\na compound page, but not the master page in that compound page.  This case\ncan occur via access_process_vm() if you attemp to write to another\nprocess\u0027s hugepage memory area using ptrace() (causing an oops or hang).\n\nThis patch fixes the bug by only calling set_page_dirty() from\naccess_process_vm() if the page is not a compound page.  We already use a\nsimilar fix in bio_set_pages_dirty() for the case of direct io to\nhugepages.\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nAcked-by: William Irwin \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
