SYNOPSIS

DESCRIPTION

16       Allocate a new sk_buff and assign it a usage count of one. The buffer
17       has unspecified headroom built in. Users should allocate the headroom
18       they think they need without accounting for the built in space. The
19       built in space is used for optimisations.

21       NULL is returned if there is no free memory. Although this function
22       allocates memory it can be called from an interrupt.
