But as netlink socket needs a compare function to look for an object, we first introduce a new function called rhashtable_lookup_compare_insert() in commit #1 which is implemented based on original rhashtable_lookup_insert(). We subsequently remove nl_sk_hash_lock from netlink socket with the new introduced function in commit #2. Lastly, as Thomas requested, we add commit #3 to indicate the implementation of what the grow and shrink decision function must enforce min/max shift. v2: As Thomas pointed out, there was a race between checking portid and then setting it in commit #2. Now use socket lock to make the process of both checking and setting portid atomic, and then eliminate the race. ==================== Signed-off-by: David S.
