Put this into "fake_inode.d":
Code:
syscall::stat64:entry, syscall::lstat64:entry
/strstr(copyinstr(arg0), "passwd") != NULL/
{
  self->statptr = arg1;
}

syscall::stat64:return, syscall::lstat64:return
/self->statptr != NULL && curpsinfo->pr_dmodel == PR_MODEL_ILP32/
{
  self->st64_32 = (struct stat64_32 *)copyin(self->statptr, sizeof(struct stat64_32));
  self->st64_32->st_ino = 100000000000;
  copyout(self->st64_32, self->statptr, sizeof(struct stat64_32));
}

syscall::stat64:return, syscall::lstat64:return
/self->statptr != NULL && curpsinfo->pr_dmodel == PR_MODEL_LP64/
{
  self->st64 = (struct stat64 *)copyin(self->statptr, sizeof(struct stat64));
  self->st64->st_ino = 100000000000;
  copyout(self->st64, self->statptr, sizeof(struct stat64));
}

Replace "passwd" with whatever filename you want to fake inode for. Then run:
Code:
dtrace -w -s fake_inode.d

In the other terminal run:
Code:
ls -li /etc/passwd

Change the filename of the file that you are checking with "ls", if you changed the filename in the "fake_inode.d" script. This should produce:
Code:
# ls -li /etc/passwd
100000000000 -rw-r--r--   1 root     sys         1972 Jun 13  2013 /etc/passwd
