On the one hand, mddev_unlock() will call md_wakeup_thread() unconditionally; on the other hand, md_check_recovery() can't make progress if 'reconfig_mutex' can't be grabbed. Hence, it really doesn't make sense to wake up daemon thread while 'reconfig_mutex' is still grabbed. Remove all the md_wakup_thread() for 'mddev->thread' while 'reconfig_mtuex' is still grabbed.

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.
