	I just looked, and they all have the di (well, it's called fe in
mknod_locked, but it is still there.  the aops.c functions have it on
the write_ctxt).  I agree with Tao, max_inline_data_with_xattr() is
always the correct function.
	Btw, in mknod, it's safe to call.  The INLINE_XATTR_FL will
*not* be set, which is correct with regards to your previous patch (that
makes sure a block is reserved for the xattrs on an inline directory).
	Good catch!

Joel
