[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.2.53-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Nikhil P Rao <nikhil.rao@xxxxxxxxx>

commit d6776e6d5c2f8db0252f447b09736075e1bbe387 upstream.

_pci_assign_resource() took an int "size" argument, which meant that
sizes larger than 4GB were truncated.  Change type to resource_size_t.
