R. Silva\" \n\n-Wflex-array-member-not-at-end was introduced in GCC-14, and we are\ngetting ready to enable it, globally.\n\nUse the TRAILING_OVERLAP() helper to fix the following warnings:\n\n1 net/netfilter/x_tables.c:816:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]\n1 net/netfilter/x_tables.c:811:39: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]\n\nThis helper creates a union between a flexible-array member (FAM)\nand a set of members that would otherwise follow it. This overlays\nthe trailing members onto the FAM while preserving the original\nmemory layout.\n\nSigned-off-by: Gustavo A. R.
