skb_copy_bits is an example of the code flow that does work.

skb_seq_read appears to only be used by iSCSI and the skb text match

There is no reason iscsi needs to use skb_seq_read. It used to use 
skb_copy_bits. I can convert iscsi to use skb_copy_bits again.

Is it easier to just convert the text search to not use skb_seq_read, 
and then just dump those functions?
