From 2bab480d1ca9b654eff316eba44fad2eac8884b4 Mon Sep 17 00:00:00 2001 From: James Simmons Date: Wed, 23 Dec 2015 16:24:50 -0500 Subject: [PATCH] staging: lustre: return proper error code for libcfs_kkuc_msg_put The functon libcfs_kkuc_msg_put() returns -ENOSYS which is not correct. Return -ENXIO instead if the kuc header is corrupt.
