Jakub Kicinski says: ==================== net: depend on instance lock for queue related netlink ops netdev-genl used to be protected by rtnl_lock. In previous release we already switched the queue management ops (for Rx zero-copy) to the instance lock. This series converts other ops to depend on the instance lock when possible. Unfortunately queue related state is hard to lock (unlike NAPI) as the process of switching the number of queues usually involves a large reconfiguration of the driver. The reconfig process has historically been under rtnl_lock, but for drivers which opt into ops locking it is also under the instance lock. Leverage that and conditionally take rtnl_lock or instance lock depending on the device capabilities. v1: https://lore.kernel.org/20250407190117.16528-1-kuba@kernel.org ==================== Link: https://patch.msgid.link/20250408195956.412733-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
