3fb2d124b6Several places in init/do_mounts.c allocate temporary buffers for filesystem names or options using __get_free_page() or alloc_page(). Usage of alloc_page() APIs is not required there and only creates unnecessary noise with castings or conversion from struct page to void *. kmalloc() is a better API for these uses and it also provides better scalability and more debugging possibilities. Replace use of __get_free_page() and alloc_page() with kmalloc(). While on it, add a check for -ENOMEM condition in mount_root_generic().
