Subject: [PATCH 0/2][next] Add STACK_FLEX_ARRAY_SIZE() helper

Add new STACK_FLEX_ARRAY_SIZE() helper to get the size of a
flexible-array member defined using DEFINE_FLEX()/DEFINE_RAW_FLEX()
at compile time.

This is essentially the same as ARRAY_SIZE() but for on-stack
flexible-array members.

Gustavo A. R. Silva (2):
  overflow: Add STACK_FLEX_ARRAY_SIZE() helper
  kunit/overflow: Add tests for STACK_FLEX_ARRAY_SIZE() helper
