2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Arjan van de Ven fixed upstream in commit b7058842c940ad2c08dd829b21e5c92ebe3b8758 in a different way The length of the to-copy data structure is currently stored in a signed integer. However many comparisons are done with sizeof(..) which is unsigned. It's more suitable for this variable to be unsigned to make these comparisons more naturally right.
