[ Upstream commit c4595fe394a289927077e3da561db27811919ee0 ] Since commit14072ee33d("ubi: fastmap: Check wl_pool for free peb before wear leveling"), wear_leveling_worker() won't schedule fm_work if wear-leveling pool is empty, which could temporarily disable the wear-leveling until the fastmap is updated(eg. pool becomes empty). Fix it by scheduling fm_work if wl_pool is empty during wear-leveing.

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.
