It shouldn't make the structure larger since there's a hole in the structure:
unsigned int sk_padding : 2,
sk_no_check_tx : 1,
sk_no_check_rx : 1,
sk_userlocks : 4,
sk_protocol : 8,
sk_type : 16;
#define SK_PROTOCOL_MAX U8_MAX
kmemcheck_bitfield_end(flags);
u16 sk_gso_max_segs;
---> 2-byte hole here
unsigned long sk_lingertime;
but I'll quite happily shift it to sk_padding.
Thanks,
David
