Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH][next] io_uring: replace zero-length array with flexible-array member 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].
