Description
Duplicate an sk_buff. The new one is not owned by a socket. Both copies share the same packet data but not structure. The new buffer has a reference count of 1. If the allocation fails the function returns NULL otherwise the new buffer is returned.
If this function is called from an interrupt gfp_mask must be GFP_ATOMIC.
