I'm back-porting this driver to 4.1
skb_free_frag() was introduced in 4.2 by 181edb2bfa22b IIUC.
+static inline void skb_free_frag(void *addr)
+{
+ __free_page_frag(addr);
+}
Should I just copy the definition of __free_page_frag() ?
/*
* Frees a page fragment allocated out of either a compound or order 0 page.
*/
void __free_page_frag(void *addr)
{
struct page *page = virt_to_head_page(addr);
if (unlikely(put_page_testzero(page)))
__free_pages_ok(page, compound_order(page));
}
Regards.
