From ed73a505480d5413675a5a5a79466d5c661f88c2 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 9 Jan 2023 19:40:22 -0600 Subject: [PATCH] RDMA/erdma: Replace zero-length arrays with flexible-array members Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length arrays, in a couple of structures, with flex-array members. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].
