When unpacking the initramfs or when mounting block devices we need to ensure that any delayed fput() finished to prevent spurious errors. The init process can be a proper kernel thread or a user mode helper. In the latter case PF_KTHREAD isn't set. So we need to do both flush_delayed_work() and task_work_run(). Since we'll port block device opening and closing to regular file open and closing we need to ensure the same as for the initramfs. So just make that a little helper.

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.
