From: Miklos Szeredi <[EMAIL PROTECTED]>
Pass the open file into the filesystem's ->getattr() method for
fstat().
This is needed to be able to correctly implement open-unlink-fstat
semantics in some filesystem such as sshfs, without having to resort
to "silly-renaming".
Do this by adding a 'struct file *' parameter to i_op->getattr(). For
fstat() pass the open file pointer, in other cases pass NULL.
This is safe from a compatibility standpoint, out-of-tree old stuff
will continue to work, but will get a warning at compile time.
