Seems to be a sensitive lock, where ct->lock looks to be primed with fs_reclaim, so holding that and then allocating memory will cause lockdep to complain. We need to change the ordering wrt to grabbing the ct->lock and potentially grabbing the runtime_pm, since some of the runtime_pm routines can allocate memory (or at least that's what lockdep seems to suggest).

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.
