As I can see it, sk_buff can be on double-linked list,
and then it is linked by next and prev,
or it is referenced by red-black tree, rb_node,
depending of some network logic (packet type ?)

Both are used by functions operating on structures.

Struct sk_buff_head

[wiktoria.lewicka]

Hello!
I read code from file include/linux/skbuff.h and I have question about 
sk_buff_head structure. This structure is pointing to next and prev sk_buff 
structure on list. But I found the same pointers in first field structure 
sk_buff- it is union, which has pointers to next and prev sk_buff structures on 
list. Is this union replace sk_buff_head structure? I didn`t found any field in 
sk_buff, which may use sk_buff_head, but I found some functions which uses this 
structure.
