Changing it to *_put makes it more consistent and makes it easier to understand the connection to the *_get functions. Signed-off-by: Sven Eckelmann --- v7: - removed patches which are now applied in the branch master - split *_get -> *_put rename patches into smaller patches only renaming single functions v6: - removed patches which are now applied in the branch next - rebased remaining patches on the patch "batman-adv: Avoid recursive call_rcu for batadv_nc_node" which was modified by Marek while he applied the patches (this unfortunately made some of the remaining patches slightly harder to apply) v5: - add hack which allows to compile against stable kernel like 3.2.44 which also added the kref_get_unless_zero function v4: - fix function names in commit messages - fix double whitespace in batadv_tt_orig_list_entry_release kerneldoc - add extra patch for batadv_claim_free_ref kerneldoc fix - change the phrase "free it" in all *_free_ref/*_put functions to "release it" v3: - update copyright year v2: - split patchset into fixes and kref migration to make it easier when the decision is made where each patch will be applied net/batman-adv/bridge_loop_avoidance.c | 25 ++++++++++++------------- 1 file changed, 12 insertions(+), 13 deletions(-) diff --git a/net/batman-adv/bridge_loop_avoidance.c b/net/batman-adv/bridge_loop_avoidance.c index b7167cf..ce2d070 100644 --- a/net/batman-adv/bridge_loop_avoidance.c +++ b/net/batman-adv/bridge_loop_avoidance.c @@ -159,12 +159,11 @@ static void batadv_backbone_gw_release(struct kref *ref) } /** - * batadv_backbone_gw_free_ref - decrement the backbone gw refcounter and - * possibly release it + * batadv_backbone_gw_put - decrement the backbone gw refcounter and possibly + * release it * @backbone_gw: backbone gateway to be free'd */ -static void -batadv_backbone_gw_free_ref(struct batadv_bla_backbone_gw *backbone_gw) +static void batadv_backbone_gw_put(struct batadv_bla_backbone_gw *backbone_gw) { kref_put(&backbone_gw->refcount, batadv_backbone_gw_release); } @@ -180,7 +179,7 @@ static void batadv_claim_release(struct kref *ref) claim = container_of(ref, struct batadv_bla_claim, refcount); - batadv_backbone_gw_free_ref(claim->backbone_gw); + batadv_backbone_gw_put(claim->backbone_gw); kfree_rcu(claim, rcu); } @@ -524,7 +523,7 @@ batadv_bla_update_own_backbone_gw(struct batadv_priv *bat_priv, return; backbone_gw->lasttime = jiffies; - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); } /** @@ -573,7 +572,7 @@ static void batadv_bla_answer_request(struct batadv_priv *bat_priv, /* finally, send an announcement frame */ batadv_bla_send_announce(bat_priv, backbone_gw); - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); } /** @@ -682,7 +681,7 @@ static void batadv_bla_add_claim(struct batadv_priv *bat_priv, spin_lock_bh(&claim->backbone_gw->crc_lock); claim->backbone_gw->crc ^= crc16(0, claim->addr, ETH_ALEN); spin_unlock_bh(&claim->backbone_gw->crc_lock); - batadv_backbone_gw_free_ref(claim->backbone_gw); + batadv_backbone_gw_put(claim->backbone_gw); } /* set (new) backbone gw */ kref_get(&backbone_gw->refcount); @@ -783,7 +782,7 @@ static int batadv_handle_announce(struct batadv_priv *bat_priv, u8 *an_addr, } } - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); return 1; } @@ -854,7 +853,7 @@ static int batadv_handle_unclaim(struct batadv_priv *bat_priv, claim_addr, BATADV_PRINT_VID(vid), backbone_gw->orig); batadv_bla_del_claim(bat_priv, claim_addr, vid); - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); return 1; } @@ -891,7 +890,7 @@ static int batadv_handle_claim(struct batadv_priv *bat_priv, /* TODO: we could call something like tt_local_del() here. */ - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); return 1; } @@ -1154,7 +1153,7 @@ purge_now: batadv_bla_del_backbone_claims(backbone_gw); hlist_del_rcu(&backbone_gw->hash_entry); - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); } spin_unlock_bh(list_lock); } @@ -1571,7 +1570,7 @@ int batadv_bla_is_backbone_gw(struct sk_buff *skb, if (!backbone_gw) return 0; - batadv_backbone_gw_free_ref(backbone_gw); + batadv_backbone_gw_put(backbone_gw); return 1; }
