Based on review, `lock' is only acquired in hwbm_pool_add() which is invoked via ->probe(), ->resume() and ->ndo_change_mtu(). Based on this the lock can become a mutex and there is no need to disable interrupts during the procedure. Now that the lock is a mutex, hwbm_pool_add() no longer invokes hwbm_pool_refill() in an atomic context so we can pass GFP_KERNEL to hwbm_pool_refill() and remove the `gfp' argument from hwbm_pool_add().

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.
