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/bat_iv_ogm.c | 16 ++++++++-------- net/batman-adv/bridge_loop_avoidance.c | 4 ++-- net/batman-adv/distributed-arp-table.c | 4 ++-- net/batman-adv/fragmentation.c | 2 +- net/batman-adv/gateway_client.c | 8 ++++---- net/batman-adv/icmp_socket.c | 2 +- net/batman-adv/main.c | 2 +- net/batman-adv/network-coding.c | 4 ++-- net/batman-adv/originator.c | 8 ++++---- net/batman-adv/originator.h | 2 +- net/batman-adv/routing.c | 18 +++++++++--------- net/batman-adv/send.c | 2 +- net/batman-adv/translation-table.c | 14 +++++++------- 13 files changed, 43 insertions(+), 43 deletions(-) diff --git a/net/batman-adv/bat_iv_ogm.c b/net/batman-adv/bat_iv_ogm.c index bf0e7d6..32df38b 100644 --- a/net/batman-adv/bat_iv_ogm.c +++ b/net/batman-adv/bat_iv_ogm.c @@ -287,8 +287,8 @@ batadv_iv_ogm_orig_get(struct batadv_priv *bat_priv, const u8 *addr) free_orig_node: /* free twice, as batadv_orig_node_new sets refcount to 2 */ - batadv_orig_node_free_ref(orig_node);
