Jiapeng,
Aurelien is correct, you should respin this patch and correct for
where it breaks the sizeof calculation.  For example your change:

struct smb2_lock_rsp {

@@ -1434,7 +1434,7 @@ struct smb2_query_directory_req {
        __le16 FileNameOffset;
        __le16 FileNameLength;
        __le32 OutputBufferLength;
-       __u8   Buffer[1];
+       __u8   Buffer[];
 } __packed;

would have the side effect of making the file name off by one:

smb2pdu.c-4654- req->FileNameOffset =
smb2pdu.c:4655:         cpu_to_le16(sizeof(struct
smb2_query_directory_req) - 1);

Hi Jiapeng,

This will change the size returned by sizeof(). Have you checked that
this doesn't introduce off-by-one errors in all the sizeof() usage?

Cheers,
