-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally.
Use the new TRAILING_OVERLAP() helper to fix the following warning: net/tls/tls.h:131:29: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] This helper creates a union between a flexible-array member (FAM) and a set of members that would otherwise follow it. This overlays the trailing members onto the FAM while preserving the original memory layout. Signed-off-by: Gustavo A. R.
