Acceleration in SRCU happens on enqueue time for each new callback. This operation is expected not to fail and therefore any similar attempt from other places shouldn't find any remaining callbacks to accelerate. Moreover accelerations performed beyond enqueue time are error prone because rcu_seq_snap() then may return the snapshot for a new grace period that is not going to be started. Remove these dangerous and needless accelerations and introduce instead assertions reporting leaking unaccelerated callbacks beyond enqueue time.

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.
