Message-Id: <20111102222746.727195520@clark.kroah.org> Date: Wed, 02 Nov 2011 15:27:00 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, "J. Bruce Fields" <bfields@...hat.com> Subject: [076/101] nfsd4: ignore WANT bits in open downgrade 2.6.33-longterm review patch. If anyone has any objections, please let us know. ------------------ From: "J. Bruce Fields" <bfields@...hat.com> commit c30e92df30d7d5fe65262fbce5d1b7de675fe34e upstream. We don't use WANT bits yet--and sending them can probably trigger a BUG() further down. Signed-off-by: J.
