VFS version error

[Sharayu Mantri]

Okay, So I want to intercept Open , close, read, write, create file, and
various similar directory calls . If any file is opened from the shared
folder in client , that moment before the VFS open call, my function should
be executed which takes the details of the file which is opened , like path
, last accesed, last modified, and various other. and update that into my
berkeley database.
after updation move the file from directory to some other directory
(depending on policy , logic of project ) and after moving open system call
can be executed.

So, what i need is the open call to be called only once for each. Is that
possible ? If not what other options I have?
Thanks
