    adding &page->lru into the pagelist tail in fb_deferred_io_mkwrite(), another process is re-initializing
    the same &page->lru in fb_deferred_io_fault(), which is not protected by the lock. This fix is to init all
    the page lists one time during initialization, it not only fixes the list corruption, but also avoids
    INIT_LIST_HEAD() redundantly. V2: change int i to unsigned int i (Geert Uytterhoeven) (CVE-2022-49511)
