From: Gustavo A. R. Silva <gustavoars@xxxxxxxxxx> ACPICA commit 98835f452c698b015d4da999944405ecb90da670 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].
