Percpu reference counters should now be initialized with the PERCPU_REF_ALLOW_REINIT in order to allow switching them to the percpu mode from the atomic mode. To make percpu_ref_switch_to_percpu() call in set_in_sync() succeed,let's initialize percpu refcounters with the PERCU_REF_ALLOW_REINIT flag.

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.
