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].

This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)

@@ identifier S, member, array; type T1, T2; @@

struct S { ... T1 member; T2 array[ - 0 ]; };

UAPI and wireless changes were intentionally excluded from this patch and will be sent out separately.

Link: https://github.com/KSPP/linux/issues/78 Signed-off-by: Gustavo A. R. Silva gustavoars@kernel.org --- Hi all,

I'm expecting to carry this patch in my tree, so it'd be great to get some Acks. And given the size of the patch, I'm only sending this to mailing lists.

Thanks!
