First -we move the page_frag_ portion of the name to the front of the functions -names. Secondly we split out the cache specific functions from the -other page fragment functions by adding the word "cache" to the name. - -Finally I added a bit of documentation that will hopefully help to -explain some of this. I plan to revisit this later as we get things -more ironed out in the near future with the changes planned for the DMA -setup to support eXpress Data Path. - -This patch (of 3): - -This patch renames the page frag functions to be more consistent with -other APIs. Specifically we place the name page_frag first in the name -and then have either an alloc or free call name that we append as the -suffix. This makes it a bit clearer in terms of naming. - -In addition we drop the leading double underscores since we are -technically no longer a backing interface and instead the front end that -is called from the networking APIs. - -Link: http://lkml.kernel.org/r/20170104023854.13451.67390.stgit@localhost.localdomain -Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> -Signed-off-by: Andrew Morton <akpm@linux-foundation.org> -Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> ---- - ---- a/include/linux/gfp.h -+++ b/include/linux/gfp.h -@@ -508,9 +508,9 @@ extern void free_hot_cold_page_list(stru - struct page_frag_cache; - extern void __page_frag_drain(struct page *page, unsigned int order, - unsigned int count); --extern void *__alloc_page_frag(struct page_frag_cache *nc, -- unsigned int fragsz, gfp_t gfp_mask); --extern void __free_page_frag(void *addr); -+extern void *page_frag_alloc(struct page_frag_cache *nc, -+ unsigned int fragsz, gfp_t gfp_mask); -+extern void page_frag_free(void *addr); - - #define __free_page(page) __free_pages((page), 0) - #define free_page(addr) free_pages((addr), 0) ---- a/include/linux/skbuff.h -+++ b/include/linux/skbuff.h -@@ -2476,7 +2476,7 @@ static inline struct sk_buff *netdev_all - - static inline void skb_free_frag(void *addr) - { -- __free_page_frag(addr); -+ page_frag_free(addr); - } - - void *napi_alloc_frag(unsigned int fragsz); ---- a/mm/page_alloc.c -+++ b/mm/page_alloc.c -@@ -3949,8 +3949,8 @@ void __page_frag_drain(struct page *page - } - EXPORT_SYMBOL(__page_frag_drain); - --void *__alloc_page_frag(struct page_frag_cache *nc, -- unsigned int fragsz, gfp_t gfp_mask) -+void *page_frag_alloc(struct page_frag_cache *nc, -+ unsigned int fragsz, gfp_t gfp_mask) - { - unsigned int size = PAGE_SIZE; - struct page *page; -@@ -4001,19 +4001,19 @@ refill: - - return nc->va + offset; - } --EXPORT_SYMBOL(__alloc_page_frag); -+EXPORT_SYMBOL(page_frag_alloc); - - /* - * Frees a page fragment allocated out of either a compound or order 0 page. - */ --void __free_page_frag(void *addr) -+void page_frag_free(void *addr) - { - struct page *page = virt_to_head_page(addr); - - if (unlikely(put_page_testzero(page))) - __free_pages_ok(page, compound_order(page)); - } --EXPORT_SYMBOL(__free_page_frag); -+EXPORT_SYMBOL(page_frag_free); - - static void *make_alloc_exact(unsigned long addr, unsigned int order, - size_t size) ---- a/net/core/skbuff.c -+++ b/net/core/skbuff.c -@@ -369,7 +369,7 @@ static void *__netdev_alloc_frag(unsigne - - local_irq_save(flags); - nc = this_cpu_ptr(&netdev_alloc_cache); -- data = __alloc_page_frag(nc, fragsz, gfp_mask); -+ data = page_frag_alloc(nc, fragsz, gfp_mask); - local_irq_restore(flags); - return data; - } -@@ -393,7 +393,7 @@ static void *__napi_alloc_frag(unsigned - { - struct napi_alloc_cache *nc = this_cpu_ptr(&napi_alloc_cache); - -- return __alloc_page_frag(&nc->page, fragsz, gfp_mask); -+ return page_frag_alloc(&nc->page, fragsz, gfp_mask); - } - - void *napi_alloc_frag(unsigned int fragsz) -@@ -445,7 +445,7 @@ struct sk_buff *__netdev_alloc_skb(struc - local_irq_save(flags); - - nc = this_cpu_ptr(&netdev_alloc_cache); -- data = __alloc_page_frag(nc, len, gfp_mask); -+ data = page_frag_alloc(nc, len, gfp_mask); - pfmemalloc = nc->pfmemalloc; - - local_irq_restore(flags); -@@ -509,7 +509,7 @@ struct sk_buff *__napi_alloc_skb(struct - if (sk_memalloc_socks()) - gfp_mask |= __GFP_MEMALLOC; - -- data = __alloc_page_frag(&nc->page, len, gfp_mask); -+ data = page_frag_alloc(&nc->page, len, gfp_mask); - if (unlikely(!data)) - return NULL; - |
