Stanislav Fomichev says: ==================== net: Hold netdev instance lock during ndo operations As the gradual purging of rtnl continues, start grabbing netdev instance lock in more places so we can get to the state where most paths are working without rtnl. Start with requiring the drivers that use shaper api (and later queue mgmt api) to work with both rtnl and netdev instance lock. Eventually we might attempt to drop rtnl. This mostly affects iavf, gve, bnxt and netdev sim (as the drivers that implement shaper/queue mgmt) so those drivers are converted in the process. call_netdevice_notifiers locking is very inconsistent and might need a separate follow up. Some notified events are covered by the instance lock, some are not, which might complicate the driver expectations.

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.
