Hi, I'm trying to work out why the skb is cloned in recv_pkt in net/bluetooth/6lowpan.c when performing IPHC [0]. I would like to call process_data with an unshared skb as my proposal for the next patch is to use pskb_expand_head[1] in the decompression routine to save copying but this requires an skb with users == 1 otherwise it will call BUG(). In light of the locking problem Jukka was seeing with my previous patch I'm wondering if me removing this skb_clone was the cause so I want to make sure I know what it's there for before sending the patch. Any help is appreciated. - Martin.
