Message-ID: <YxKNA/3add4wxI3R@work> Date: Sat, 3 Sep 2022 00:08:51 +0100 From: "Gustavo A. R. Silva" <gustavoars@...nel.org> To: Cc: linux-kernel@...r.kernel.org, "Gustavo A. R. Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org, ; Subject: [PATCH][next] 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.
