Subject: [PATCH rdma-next v1 08/15] RDMA/core: Remove the kobject_uevent() NOP
Date: Mon, 7 Jun 2021 11:17:33 +0300 [thread overview]
Message-ID: <0d1deca036afe09cdddd9bead8cb6e0a6e52be60.1623053078.git.leonro@nvidia.com> (raw)
In-Reply-To: <cover.1623053078.git.leonro@nvidia.com>
From: Jason Gunthorpe <jgg@nvidia.com>
This call does nothing because the ib_port kobj is nested under a struct
device kobject and the dev_uevent_filter() function of the struct device
blocks uevents for any children kobj's that are not also struct devices.
A uevent for the struct device will be triggered after
ib_setup_port_attrs() returns which causes udev to pick up all the deep
"attributes" which are implemented as kobjects nested under a struct
device and assign them to the udev object for the struct device:
$ udevadm info -a /sys/class/infiniband/ibp0s9
ATTR{ports/1/counters/excessive_buffer_overrun_errors}=="0"
