Naoya Horiguchi ff604cf6d4 mm: hwpoison: fix action_result() to print out dirty/clean ... action_result() fails to print out "dirty" even if an error occurred on a dirty pagecache, because when we check PageDirty in action_result() it was cleared after page isolation even if it's dirty before error handling. This can break some applications that monitor this message, so should be fixed. There are several callers of action_result() except page_action(), but either of them are not for LRU pages but for free pages or kernel pages, so we don't have to consider dirty or not for them. Note that PG_dirty can be set outside page locks as described in commit 6746aff74d ("HWPOISON: shmem: call set_page_dirty() with locked page"), so this patch does not completely closes the race window, but just narrows it.
