scroll buffer so that current line becomes first visible line

[Will Willis]

Hello, Is there a command/key binding to scroll my buffer so that the
current line (the one with my cursor) becomes the first visible line
in the window. This is akin to C-l, but instead of centering to the
point, sticking the current line at the top of the window. I'm _not_
looking to move the point to the first line (M-0 M-r).

I'm not sure how this would work for shorter files, say only a few
lines long, would a buffer who's length is shorter than the window
height be able to scroll?

Thanks,
Will
