Menglong Dong 0c6de0c943 net: tipc: fix FB_MTU eat two pages ... FB_MTU is used in 'tipc_msg_build()' to alloc smaller skb when memory allocation fails, which can avoid unnecessary sending failures. The value of FB_MTU now is 3744, and the data size will be: (3744 + SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) + \ SKB_DATA_ALIGN(BUF_HEADROOM + BUF_TAILROOM + 3)) which is larger than one page(4096), and two pages will be allocated. To avoid it, replace '3744' with a calculation: (PAGE_SIZE - SKB_DATA_ALIGN(BUF_OVERHEAD) - \ SKB_DATA_ALIGN(sizeof(struct skb_shared_info))) What's more, alloc_skb_fclone() will call SKB_DATA_ALIGN for data size, and it's not necessary to make alignment for buf_size in tipc_buf_acquire(). So, just remove it.
