__pskb_copy_fclone9
Create copy of an sk_buff with private head.
Usage
struct sk_buff * __pskb_copy_fclone(struct sk_buff * skb, int headroom, gfp_t gfp_mask, bool fclone);
Arguments
skb
buffer to copy
headroom
headroom of new skb
gfp_mask
allocation priority
fclone
if true allocate the copy of the skb from the fclone cache instead of the head cache; it is recommended to set this to true for the cases where the copy will likely be cloned
Overview
Make a copy of both an sk_buff and part of its data, located in header. Fragmented data remain shared. This is used when the caller wishes to modify only header of sk_buff and needs private copy of the header to alter. Returns NULL on failure or the pointer to the buffer on success. The returned buffer has a reference count of 1.
