Freeing phys_pg_pack includes calling to scrubbing functions of the device's memory, taking locks and possibly even calling reset. This is not something that should be done while holding a device-wide spinlock. Therefore, save the relevant objects on a local linked-list and after releasing the spinlock, traverse that list and free the phys_pg_pack objects. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
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.
