[PATCH] swap 3/3 unsafe Dirty check
Todd R. Eigenschink <todd@tekinteractive.com> reported 2.4 swapoff
kernel BUG at filemap.c:122 to LKML 24 May. Other problems on that
system may have contributed, but yes, despite __delete_from_swap_cache
doing ClearPageDirty before __remove_inode_page to avoid the BUG(),
a concurrent zap_pte_range might race to set_page_dirty. So skip
that oops in PageSwapCache case. Remove the prior ClearPageDirty?
maybe but not without deeper thought: let stay for now.
