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/main.c | 2 +- net/batman-adv/soft-interface.c | 14 +++++++------- net/batman-adv/soft-interface.h | 2 +- net/batman-adv/sysfs.c | 4 ++-- net/batman-adv/translation-table.c | 20 ++++++++++---------- 5 files changed, 21 insertions(+), 21 deletions(-) diff --git a/net/batman-adv/main.c b/net/batman-adv/main.c index bf8a01b..e3d7051 100644 --- a/net/batman-adv/main.c +++ b/net/batman-adv/main.c @@ -1261,7 +1261,7 @@ bool batadv_vlan_ap_isola_get(struct batadv_priv *bat_priv, unsigned short vid) vlan = batadv_softif_vlan_get(bat_priv, vid); if (vlan) { ap_isolation_enabled = atomic_read(&vlan->ap_isolation); - batadv_softif_vlan_free_ref(vlan); + batadv_softif_vlan_put(vlan); } return ap_isolation_enabled; diff --git a/net/batman-adv/soft-interface.c b/net/batman-adv/soft-interface.c index ca8fa4e..0710379 100644 --- a/net/batman-adv/soft-interface.c +++ b/net/batman-adv/soft-interface.c @@ -497,11 +497,11 @@ static void batadv_softif_vlan_release(struct kref *ref) } /** - * batadv_softif_vlan_free_ref - decrease the vlan object refcounter and + * batadv_softif_vlan_put - decrease the vlan object refcounter and * possibly release it * @vlan: the vlan object to release */ -void batadv_softif_vlan_free_ref(struct batadv_softif_vlan *vlan) +void batadv_softif_vlan_put(struct batadv_softif_vlan *vlan) { if (!vlan) return; @@ -552,7 +552,7 @@ int batadv_softif_create_vlan(struct batadv_priv *bat_priv, unsigned short vid) vlan = batadv_softif_vlan_get(bat_priv, vid); if (vlan) { - batadv_softif_vlan_free_ref(vlan); + batadv_softif_vlan_put(vlan); return -EEXIST; } @@ -601,7 +601,7 @@ static void batadv_softif_destroy_vlan(struct batadv_priv *bat_priv, vlan->vid, "vlan interface destroyed", false); batadv_sysfs_del_vlan(bat_priv, vlan); - batadv_softif_vlan_free_ref(vlan); + batadv_softif_vlan_put(vlan); } /** @@ -646,7 +646,7 @@ static int batadv_interface_add_vid(struct net_device *dev, __be16 proto, if (!vlan->kobj) { ret = batadv_sysfs_add_vlan(bat_priv->soft_iface, vlan); if (ret) { - batadv_softif_vlan_free_ref(vlan); + batadv_softif_vlan_put(vlan); return ret; } } @@ -693,7 +693,7 @@ static int batadv_interface_kill_vid(struct net_device *dev, __be16 proto, batadv_softif_destroy_vlan(bat_priv, vlan); /* finally free the vlan object */ - batadv_softif_vlan_free_ref(vlan); + batadv_softif_vlan_put(vlan); return 0; } @@ -749,7 +749,7 @@ static void batadv_softif_destroy_finish(struct work_struct *work) vlan = batadv_softif_vlan_get(bat_priv, BATADV_NO_FLAGS); if (vlan) { batadv_softif_destroy_vlan(bat_priv, vlan); - batadv_softif_vlan_free_ref(vlan); + batadv_softif_vlan_put(vlan); } batadv_sysfs_del_meshif(soft_iface); diff --git a/net/batman-adv/soft-interface.h b/net/batman-adv/soft-interface.h index d17cfba..9ae2657 100644 --- a/net/batman-adv/soft-interface.h +++ b/net/batman-adv/soft-interface.h @@ -34,7 +34,7 @@ void batadv_softif_destroy_sysfs(struct net_device *soft_iface); int batadv_softif_is_valid(const struct net_device *net_dev); extern struct rtnl_link_ops batadv_link_ops; int batadv_softif_create_vlan(struct batadv_priv *bat_priv, unsigned short vid); -void batadv_softif_vlan_free_ref(struct batadv_softif_vlan *softif_vlan); +void batadv_softif_vlan_put(struct batadv_softif_vlan *softif_vlan); struct batadv_softif_vlan *batadv_softif_vlan_get(struct batadv_priv *bat_priv, unsigned short vid); diff --git a/net/batman-adv/sysfs.c b/net/batman-adv/sysfs.c index 0db7591..4d70d44 100644 --- a/net/batman-adv/sysfs.c +++ b/net/batman-adv/sysfs.c @@ -216,7 +216,7 @@ ssize_t batadv_store_vlan_##_name(struct kobject *kobj, \ attr, &vlan->_name, \ bat_priv->soft_iface); \ \ - batadv_softif_vlan_free_ref(vlan); \ + batadv_softif_vlan_put(vlan); \ return res; \ } @@ -231,7 +231,7 @@ ssize_t batadv_show_vlan_##_name(struct kobject *kobj, \ atomic_read(&vlan->_name) == 0 ?
