From: Jeff Layton Date: Tue, 17 Jun 2014 11:44:11 +0000 (-0400) Subject: nfsd: add __force to opaque verifier field casts X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f419992c1f792f2ce501585853ffc71b8f78caa1;p=linux-beck.git nfsd: add __force to opaque verifier field casts sparse complains that we're stuffing non-byte-swapped values into __be32's here. Since they're supposed to be opaque, it doesn't matter much. Just add __force to make sparse happy. Signed-off-by: Jeff Layton Reviewed-by: Christoph Hellwig Signed-off-by: J.
