Jakub Kicinski says: ==================== net: create device lookup API with reference tracking We still see dev_hold() / dev_put() calls without reference tracker getting added in new code. dev_get_by_name() / dev_get_by_index() seem to be one of the sources of those. Provide appropriate helpers. Allocating the tracker can obviously be done with an additional call to netdev_tracker_alloc(), but a single API feels cleaner. v2: - fix a dev_put() in ethtool v1: https://lore.kernel.org/all/20230609183207.1466075-1-kuba@kernel.org/ ==================== Signed-off-by: David S.

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 Restructured Text 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.
