Declare variable cache_resolve_queue_len per-namespace: moves it into struct netns_ipv6. This variable counts the number of unresolved cache entries queued in the list mfc_unres_queue. This list is kept global to all netns as the number of entries per namespace is limited to 10 (hardcoded in routine ip6mr_cache_unresolved). Entries belonging to different namespaces in mfc_unres_queue will be identified by matching the mfc_net member introduced previously in struct mfc6_cache. Keeping this list global to all netns, also allows us to keep a single timer (ipmr_expire_timer) to handle their expiration. In some places cache_resolve_queue_len value was tested for arming or deleting the timer. These tests were equivalent to testing mfc_unres_queue value instead and are replaced in this patch. At the moment, cache_resolve_queue_len is only referenced in init_net. Signed-off-by: Benjamin Thery Signed-off-by: David S. Miller --- Reading git-diff-tree failed
