This is bad code and needs fixing.

Some problems :

New vfs function, 

bool (*aio_force)(struct vfs_handle_struct *handle, struct files_struct

defined in the code as :

int vfswrap_aio_force(struct vfs_handle_struct *handle, struct
files_struct *fsp)



int vfswrap_is_offline(struct vfs_handle_struct *handle, struct
connection_struct *conn, const char *path, SMB_STRUCT_STAT *sbuf, bool

Looks like a question for which the correct return is a bool.
But it returns a tristate, 1, 0, -1. WHAT DO THESE THINGS MEAN ?

This is just after 120 minutes looking at the code.....

This design should have been discussed on samba-technical,
not just dumped into the repository.
