When root domain non-destructive changes (e.g., only modifying one of the existing root domains while the rest is not touched) happen we still need to clear DEADLINE bandwidth accounting so that it's then properly restored, taking into account DEADLINE tasks associated to each cpuset (associated to each root domain). After the introduction of dl_servers, we fail to restore such servers contribution after non-destructive changes (as they are only considered on destructive changes when runqueues are attached to the new domains). Fix this by making sure we iterate over the dl_servers attached to domains that have not been destroyed and add their bandwidth contribution back correctly.

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.
