I have another question, samba VFS module doesn't allow to use strcpy/strcat/sprintf, and if I use the safe version such as fstrcpy, but I got __unsafe_string_function_usage_here__, how can I get safe string function for samba module using.

Thanks for your advice, and I will update it to a new version, with your excellent paper "Writing a Samba VFS", I wrote a VFS module, but when I debug the samba code, I found a strange thing, the close operation always is delayed about 15 seconds when I do a file copy, can the close operation be called just after writing all data immediately?

Even 3.6.9 is really old, and you should try to use something more recent. The SerNet folks were making source and binary RPMs available for more recent version of 3.6, so you should probably go with those if you want to stick with a 3.6.x version, and installing their RPMs is not so hard.
I notice that the latest there is from March in 2014 which is quite recent:
However, for Samba 4 you will need to register with them, as it says
Building an RPM from their source RPM is also not that hard, especially as it seems you want to make some mods.
