Subject: [PATCH 0/2][next] Add STACK_FLEX_ARRAY_SIZE() helper
Date: Tue, 22 Apr 2025 11:20:40 -0600 [thread overview]
Message-ID: <cover.1745342381.git.gustavoars@kernel.org> (raw)
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.

overflow: Add STACK_FLEX_ARRAY_SIZE() helper
kunit/overflow: Add tests for STACK_FLEX_ARRAY_SIZE() helper
