From 125217e0967fc905be35a3b2c9ba4db9a8616b92 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Tue, 25 May 2021 18:00:38 -0500 Subject: i40e: Replace one-element 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]. Refactor the code according to the use of a flexible-array member in struct i40e_qvlist_info instead of one-element array, and use the struct_size() helper.
