In order for RCU Tasks to reliably maintain per-CPU lists of exiting tasks, those lists must be initialized before it is possible for tasks to exit, especially given that the boot CPU is not necessarily CPU 0 (an example being, powerpc kexec() kernels). And at the time that rcu_init_tasks_generic() is called, a task could potentially exit, unconventional though that sort of thing might be. This commit therefore moves the calls to cblist_init_generic() from functions called from rcu_init_tasks_generic() to a new function named tasks_cblist_init_generic() that is invoked from rcu_init(). This constituted a bug in a commit that never went to mainline, so there is no need for any backporting to -stable. Reported-by: Frederic Weisbecker <frederic@kernel.org> 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.
