From d16073389bb48a2caf7c62cd7089a2009c8717b8 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 8 May 2017 09:34:04 +0200 Subject: [PATCH] lockd: fix encoder callback prototypes Declare the p_encode callbacks with the proper prototype instead of casting to kxdreproc_t and losing all type safety.
