Subject: params: Replace zero-length array with flexible-array member
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fa29c9c11d4e2ba514421758991e5b3095642844;p=linux.git

params: 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].
