H A Dtruncate.cdiff a649fd9271773dd0f78e2b9f347bcceecb8827f9 Tue Oct 17 02:09:36 CDT 2006 Andrew Morton <akpm@osdl.org> [PATCH] invalidate: remove_mapping() fix

If remove_mapping() failed to remove the page from its mapping, don't go and
mark it not uptodate! Makes kernel go dead.

(Actually, I don't think the ClearPageUptodate is needed there at all).

Says Nick Piggin:

"Right, it isn't needed because at this point the page is guaranteed
by remove_mapping to have no references (except us) and cannot pick
up any new ones because it is removed from pagecache.

We can delete it."
