Hello George Zhang,
The patch 1f166439917b: "VMCI: guest side driver implementation."
from Jan 8, 2013, leads to the following warning:
drivers/misc/vmw_vmci/vmci_guest.c:89 vmci_get_vm_context_id()
warn: always true condition '(result >= 0) => (0-u32max >= 0)'
drivers/misc/vmw_vmci/vmci_guest.c
78 u32 vmci_get_vm_context_id(void)
79 {
80 if (vm_context_id == VMCI_INVALID_ID) {
81 u32 result;
82 struct vmci_datagram get_cid_msg;
83 get_cid_msg.dst =
84 vmci_make_handle(VMCI_HYPERVISOR_CONTEXT_ID,
85 VMCI_GET_CONTEXT_ID);
86 get_cid_msg.src = VMCI_ANON_SRC_HANDLE;
87 get_cid_msg.payload_size = 0;
88 result = vmci_send_datagram(&get_cid_msg);
89 if (result >= 0)
^^^^^^^^^^^
Always true because result is an unsigned int.
90 vm_context_id = result;
regards,
dan carpenter
