RDMA/cm: Move debug counters to be under relevant IB device
The sysfs layout is created by CM incorrectly presented RDMA devices with InfiniBand link layer. Layout of such devices represents device tree of connections. By moving CM statistics to be under relevant port of IB device, we will fix the following issues: * Symlink name - It used device name instead of specific identifier. * Target location - It was supposed to point to PCI-ID/infiniband_cm/ instead of PCI-ID/infiniband/ * Target name - It created extra device file under already existing device folder, e.g. mlx5_0/mlx5_0 * Crash during boot with RDMA persistent naming patches. sysfs: cannot create duplicate filename '/class/infiniband_cm/mlx5_0' CPU: 29 PID: 433 Comm: modprobe Not tainted 5.0.0-rc5+ #178 Call Trace: dump_stack+0xcc/0x180 sysfs_warn_dup.cold.3+0x17/0x2d sysfs_do_create_link_sd.isra.2+0xd0/0xf0 device_add+0x7cb/0x1450 device_create_groups_vargs+0x1ae/0x220 device_create+0x93/0xc0 cm_add_one+0x38f/0xf60 [ib_cm] add_client_context+0x167/0x210 [ib_core] enable_device_and_get+0x230/0x3f0 [ib_core] ib_register_device+0x823/0xbf0 [ib_core] __mlx5_ib_add+0x45/0x150 [mlx5_ib] mlx5_ib_add+0x1b3/0x5e0 [mlx5_ib] mlx5_add_device+0x130/0x3a0 [mlx5_core] mlx5_register_interface+0x1a9/0x270 [mlx5_core] do_one_initcall+0x14f/0x5de do_init_module+0x247/0x7c0 load_module+0x4c2f/0x60d0 entry_SYSCALL_64_after_hwframe+0x49/0xbe After this change: [leonro@server ~]$ ls -al /sys/class/infiniband/ibp0s12f0/ports/1/ drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_rx_duplicates drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_rx_msgs drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_tx_msgs drwxr-xr-x 2 root root 0 Mar 11 11:17 cm_tx_retries Fixes: 110cf374a809 ("infiniband: make cm_device use a struct device and not a kobject.")
