lib/stackdepot.c: replace one-element array with flexible-array member Patch series "lib/stackdepot.c: Replace one-element array with flexible-array member". This series aims to replace a one-element array with a flexible-array member. Also, make use of the struct_size(), flexible_array_size() and array_size() helpers. This patch (of 3): 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]. Refactor the code according to the use of a flexible-array member in struct stack_record, instead of a one-element array, and use the struct_size() helper to calculate the size for the allocation.
