This series introduces three patches related to the kernel parameters controlling mTHP. The first patch is a straightforward documentation update, correcting the format of the kernel parameter ``thp_anon=``. The second and third patches focus on controlling THP support for shmem via the kernel command line. The second patch introduces a parameter to control the global default huge page allocation policy for the internal shmem mount. The third patch implements a parameter similar to ``thp_anon=``, but for shmem. The goal of these changes is to simplify the configuration of systems that rely on mTHP support for shmem. For instance, a platform with a GPU that benefits from huge pages may want to enable huge pages for shmem. Having these kernel parameters streamlines the configuration process and ensures consistency across setups. Regarding the third patch, I’m open to suggestions on how to reduce code duplication between ``thp_anon=`` and ``thp_shmem=``. While I duplicated the ``get_order_from_str()`` function, I realize this isn’t ideal and would appreciate advice on where best to place the function. Let me know your thoughts.
