[PATCH] Remove function prototype inside function

[Anton Blanchard <anton@samba.org>]

Hi,

I had a problem when compiling a 2.6 kernel with gcc 3.5 CVS. The
prototype for prio_tree_remove in mm/prio_tree.c is inside another
function. gcc 3.5 gets upset and removes the function completely.
Apparently this isnt valid C, so lets fix it up.

Details can be found here:
