#     printk: ringbuffer: 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].
#
