The rcutree_migrate_callbacks() invokes rcu_advance_cbs() on both the offlined CPU's ->cblist and that of the surviving CPU, then merges them. However, after the merge, and of the offlined CPU's callbacks that were not ready to be invoked will no longer be associated with a grace-period number. This commit therefore invokes rcu_advance_cbs() one more time on the merged ->cblist in order to assign a grace-period number to these callbacks. Signed-off-by: Paul E.

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.
