Comment 2 for bug 1732746

Iniital checks on testbed setup

1. dkms build against Trusty base kernel 3.13.0-135-generic - ok
2. dkms build against current Trusty HWE kernel 4.4.0-98-generic - ok
3. build against proposed Trusty HWE kernel 4.4.0-101-generic - the reported error

In detail it is:
/var/lib/dkms/iscsitarget/1.4.20.3+svn499/build/kernel/nthread.c: In function ‘do_recv’:
/var/lib/dkms/iscsitarget/1.4.20.3+svn499/build/kernel/nthread.c:129:2: error: too many arguments to function ‘sock_recvmsg’
  res = sock_recvmsg(conn->sock, &msg, len, MSG_DONTWAIT | MSG_NOSIGNAL);
