Commit 5fa5ae605821 ("netpoll: add net device refcount tracker to struct netpoll")
was part of one of the initial netdev tracker introduction patches.
It added an explicit netdev_tracker_alloc() for netpoll, presumably
because the flow of the function is somewhat odd.
After most of the core networking stack was converted to use
the tracking hold() variants, netpoll's call to old dev_hold()
stands out a bit.
np is allocated by the caller and ready to use, we can use
netdev_hold() here, even tho np->ndev will only be set to
ndev inside __netpoll_setup().

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.
