[linux-next] LinuxNextTracking branch, master, updated. next-20170619

The following commit has been merged in the master branch: commit 59ae1d127ac0ae404baf414c434ba2651b793f46 Author: Johannes Berg johannes.berg@intel.com Date: Fri Jun 16 14:29:20 2017 +0200

networking: introduce and use skb_put_data()

A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this.

An spatch similar to the one for skb_put_zero() converts many of the places using it:

@@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); )

@@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ... ( -p = skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); | -p = (t *)skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); ) ( p2 = (t2)p; -memcpy(p2, data, sizeof(*p)); | -memcpy(p, data, sizeof(*p)); )

@@ expression skb, len, data; @@ -memcpy(skb_put(skb, len), data, len); +skb_put_data(skb, data, len);

(again, manually post-processed to retain some comments)
