From: Gustavo A. R. Silva Date: Mon, 31 Aug 2020 15:22:41 +0000 (-0500) Subject: tracepoint: Replace zero-length array with flexible-array member X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9d0a49c7023c0905ea19116cf74beb7d9611d8ac;p=linux.git tracepoint: 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].
