From 37e2b57078d412547f1c14bb83eff86ab9d92d3d Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Sat, 3 Sep 2022 00:08:51 +0100 Subject: [PATCH] exportfs: Replace zero-length array with DECLARE_FLEX_ARRAY() helper Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length array declaration in struct fid with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for a flexible-array member in a union.
