[PATCH OLK-5.10 1/4] RDMA/hns: Register notifier block of bonding events in bond_grp
by Junxian Huang 15 Aug '24

15 Aug '24

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IAGSQ9 ---------------------------------------------------------------------- Currently the notifier block of bonding events is in the hr_dev structure. bond_grp is dynamic allocated in the event handler. Since all these hr_dev would response bonding events, we had to add complicated filter to choose a suitable hr_dev to handle the events. Besides we also had to concern about the validity of bond_grp pointers in many concurrency cases as they may have been freed. Refactor the bonding event handler by: 1. allocating/deallocating bond_grp structures when driver inits/exits; 2. registering notifier block of bonding events in bond_grp Signed-off-by: Junxian Huang <huangjunxian6(a)hisilicon.com> Signed-off-by: Xinghai Cen <cenxinghai(a)h-partners.com> --- drivers/infiniband/hw/hns/hns_roce_bond.c | 397 +++++++++++--------- drivers/infiniband/hw/hns/hns_roce_bond.h | 3 + drivers/infiniband/hw/hns/hns_roce_device.h | 1 - drivers/infiniband/hw/hns/hns_roce_hw_v2.c | 9 +- drivers/infiniband/hw/hns/hns_roce_main.c | 2 +- 5 files changed, 218 insertions(+), 194 deletions(-) diff --git a/drivers/infiniband/hw/hns/hns_roce_bond.c b/drivers/infiniband/hw/hns/hns_roce_bond.c index 238914c58869..a15c7b26551a 100644 --- a/drivers/infiniband/hw/hns/hns_roce_bond.c +++ b/drivers/infiniband/hw/hns/hns_roce_bond.c @@ -52,32 +52,6 @@ static int get_netdev_bond_slave_id(struct net_device *net_dev, return -ENOENT;
