+Resolve build error with linux kernel 4.8
+
+The below changes in kernel source, triggered iscsitarget
+build fail with linux kernel v4.8.
+
+1. An extra 'flags' argument has been passed to vfs_readv/vfs_writev
+   syscalls in v4.8. So, set this argument to "0" for now
+   (as there is no real need for that).

+   as they have been dropped with v4.8

+6.
+   A. The "size" argument has been dropped from sock_recvmsg syscall in v4.8,
+      as all callers have it equal to msg_data_left(msg).
+   B. 'struct user_msghdr' is being used for userland-side msghdr instead
+      of 'struct msghdr', which is used for kernel-side msghdr in linux v3.19
+      and above, so typecase it while calling sock_recvmsg syscall.
