Note that the official kernel clearly ignores it too so I'm not
reinserting any bug there but only avoiding dropping performance for no
good reason and that's why I intentionally backed out such a recent
change.
To avoiding ignoring it you should wait_on_page() (you have no other way)
and according to Trond we can't do that because the caller doesn't handle
a blocking function.
Your patch ignores locked pages too from within
invalidate_inode_pages() as far I can tell.
