VFS version error

[Sharayu Mantri]

Thank you , Now our samba and vfs_demo is runnung perfectly fine.

But while running skel_transparent.c from samba-3.6.3/examples/VFS wew got
this error

Feb 27 09:32:10 ubuntu smbd[22083]: [2015/02/27 09:32:10.287997,  0]
lib/module.c:59(do_smb_load_module)

Feb 27 09:32:10 ubuntu smbd[22083]:   vfs_init failed for service share1

let me know a way to solve this, It seems dlsym() in module.c return NULL.
but i dont find any reason. Since in similar fashion i tried to execute
vfs_demo.c and it executed prefectly.

I am attaching skel_transpaarent.c for refrence

Thank you.
