From 7206d58a3a538c80b36305d1904de313cf47ef4c Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Tue, 27 Oct 2020 01:33:56 -0500 Subject: net/smc: Replace zero-length array with flexible-array member MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].
