SKB_PAGE_FRAG_REFILL(9)                  Linux Networking                 SKB_PAGE_FRAG_REFILL(9)



NAME
       skb_page_frag_refill - check that a page_frag contains enough room

SYNOPSIS
       bool skb_page_frag_refill(unsigned int sz, struct page_frag * pfrag, gfp_t gfp);

ARGUMENTS
       sz
           minimum size of the fragment we want to get

       pfrag
           pointer to page_frag

       gfp
           priority for memory allocation

NOTE
       While this allocator tries to use high order pages, there is no guarantee that allocations
       succeed. Therefore, sz MUST be less or equal than PAGE_SIZE.
