------------------ From: Mike Rapoport <[email protected]> [ Upstream commit 7abab7b9b498650404800a08765f44929fee8f31 ] The fib6_info_alloc() function allocates percpu memory to hold per CPU pointers to rt6_info, but this memory is never freed. Fix it. Fixes: a64efe142f5e ("net/ipv6: introduce fib6_info struct and helpers") Signed-off-by: Mike Rapoport <[email protected]> Reviewed-by: David Ahern <[email protected]> Signed-off-by: David S.
