Instead of storing the @mask at the beginning of rps_sock_flow_table, use 5 low order bits of the rps_tag_ptr to store the log of the size. This removes a potential cache line miss to fetch @mask. More importantly, we can switch to vmalloc_huge() without wasting memory. Tested with: numactl --interleave=all bash -c "echo 4194304 >/proc/sys/net/core/rps_sock_flow_entries" Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Kuniyuki Iwashima <kuniyu@google.com> Link: https://patch.msgid.link/20260302181432.1836150-5-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
