Two uses of SKCIPHER_REQUEST_ON_STACK() will trigger FRAME_WARN warnings (when less than 2048) once the VLA is no longer hidden from the check: net/rxrpc/rxkad.c:398:1: warning: the frame size of 1152 bytes is larger than 1024 bytes [-Wframe-larger-than=] net/rxrpc/rxkad.c:242:1: warning: the frame size of 1152 bytes is larger than 1024 bytes [-Wframe-larger-than=] This bumps the affected objects by 20% to silence the warnings while still providing coverage is anything grows even more.
