From d247667ecd6411ec5bec9a38db7feaa599ce3ee2 Mon Sep 17 00:00:00 2001 From: Mark Bloch Date: Wed, 2 Apr 2025 10:09:44 +0300 Subject: [PATCH] RDMA/mlx5: Fix compilation warning when USER_ACCESS isn't set The cited commit made fs.c always compile, even when INFINIBAND_USER_ACCESS isn't set. This results in a compilation warning about an unused object when compiling with W=1 and USER_ACCESS is unset. Fix this by defining uverbs_destroy_def_handler() even when USER_ACCESS isn't set.
