| |
2.6.24-stable review patch. If anyone has any objections, please let us know.
------------------ From: Christoph Lameter <clameter@sgi.com>
patch 5bb983b0cce9b7b281af15730f7019116dd42568 in mainline.
gcc 4.2 spits out an annoying warning if one casts a const void * pointer to a void * pointer. No warning is generated if the conversion is done through an assignment.
