But\nthat hit will be alleviated when the long-term writable metrics\nmove to a more sharable location.\n\nSince the metrics storage went from a u32 array of RTAX_MAX entries to\nwhat is essentially a pointer, some retooling of the dst_entry layout\nwas necessary.\n\nMost importantly, we need to preserve the alignment of the reference\ncount so that it doesn\u0027t share cache lines with the read-mostly state,\nas per Eric Dumazet\u0027s alignment assertion checks.\n\nThe only non-trivial bit here is the move of the \u0027flags\u0027 member into\nthe writeable cacheline. This is OK since we are always accessing the\nflags around the same moment when we made a modification to the\nreference count.\n\nSigned-off-by: David S.
