The mptcp_sendmsg_frag helper contains a loop that will wait on the subflow sk. It seems preferrable to only wait in mptcp_sendmsg() when blocking io is requested. mptcp_sendmsg already has such a wait loop that is used when no subflow socket is available for transmission. This is a preparation patch that makes sure we call mptcp_sendmsg_frag only if a skb extension has been allocated. Moreover, such allocation currently uses GFP_ATOMIC while it could use sleeping allocation instead. Followup patches will remove the wait loop from mptcp_sendmsg_frag() and will allow to do a sleeping allocation for the extension.
