'struct llc_conn_state_trans' are not modified in this driver. Constifying this structure moves some data to a read-only section, so increase overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 13923 10896 32 24851 6113 net/llc/llc_c_st.o After: ===== text data bss dec hex filename 21859 3328 0 25187 6263 net/llc/llc_c_st.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/87cda89e4c9414e71d1a54bb1eb491b0e7f70375.1720973029.git.christophe.jaillet@wanadoo.fr Signed-off-by: Jakub Kicinski <kuba@kernel.org>
