Patch 01 converts it to use the generic kernel rhashtable which simplifies the code a lot and removes duplicated functionality. The convert also makes hash_elasticity obsolete as the generic rhashtable already has such checks and has a fixed elasticity of RHT_ELASTICITY (16 currently) so we emit a warning whenever elasticity is set and return RHT_ELASTICITY when read (patch 03). Patch 02 converts the multicast code to use non-bh RCU flavor as it was mixing bh and non-bh. Since now we have the generic rhashtable which autoshrinks we can be more liberal with the default hash maximum so patch 04 increases it to 4096 and moves it to a define in br_private.h. v3: add non-rcu br_mdb_get variant and use it where we have multicast_lock, drop special hash_max handling and just set it where needed and use non-bh RCU consistently (patch 02, new) v2: send the latest version of the set which handles when IGMP snooping is not defined, changes are in patch 01 ==================== Signed-off-by: David S.
