Linux kernel stable tree

Currently the driver either sets the initial interrupt affinity for its adminq and tx/rx queues on probe or resets it on various down/up/reconfigure flows. If any user and/or user process (i.e. irqbalance) changes IRQ affinity for any of the driver's interrupts that will be reset to driver defaults whenever any down/up/reconfigure operation happens. This is incorrect and is fixed by making 2 changes: 1. Allocate an array of cpumasks that's only allocated on probe and destroyed on remove. 2. Update the cpumask(s) for interrupts that are in use by registering for affinity notifiers.

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.
