Carsten Otte 7c81878b34 [S390] fix page change underindication in pgste_update_all ... This patch makes sure we don't underindicate _PAGE_CHANGED in case we have a race between an operation that changes the page and this code path that hits us between page_get_storage_key and page_set_storage_key. Note that we still have a potential underindication on _PAGE_REFERENCED in the unlikely event that the page was changed but not referenced _and_ someone references the page in the race window. That's not considered to be a problem. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>		2011-12-01 13:32:17 +01:00
