The bypass timer calls __call_rcu_nocb_wake() instead of directly calling __wake_nocb_gp(). The only difference here is that rdp->qlen_last_fqs_check gets overridden. But resetting the deferred force quiescent state base shouldn't be relevant for that timer. In fact the bypass queue in question can be for any rdp from the group and not necessarily the rdp leader on which the bypass timer is attached. This commit therefore calls __wake_nocb_gp() directly. This way we don't even need to lock the ->nocb_lock.

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.
