NAME

       __alloc_skb - allocate a network buffer

SYNOPSIS

       struct sk_buff * __alloc_skb  (unsigned int size, gfp_t gfp_mask,
                                         int fclone);

ARGUMENTS

       size   size to allocate

       gfp_mask
              allocation mask

       fclone allocate from fclone cache instead of head cache and allocate  a
              cloned (child) skb

DESCRIPTION

       Allocate a new &sk_buff. The returned buffer has no headroom and a tail
       room of size bytes. The object has a reference count of one. The return
       is the buffer. On a failure the return is NULL.

       Buffers  may  only  be  allocated  from  interrupts using a gfp_mask of
       GFP_ATOMIC.
