netlink: smaller nla_attr_minlen table
Length of a netlink attribute may be u16 but lengths of basic attributes are much smaller, so small we can save 16 bytes of .rodata and pocket change inside .text. 16-bit is worse on x86-64 than 8-bit because of operand size override prefix. add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-19 (-19) function old new delta validate_nla 418 417 -1 nla_policy_len 66 64 -2 nla_attr_minlen 32 16 -16 Total: Before=154865051, After=154865032, chg -0.00% Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S.
