Author: alc Date: Wed Jun 10 05:17:14 2015 New Revision: 284207 URL: https://svnweb.freebsd.org/changeset/base/284207 Log: Correct a type error in kmem_unback(). Previously, kmem_unback() did not correctly handle deallocation requests of two or more gigabytes in size. Eventually, this would lead to a panic elsewhere in the kernel, such as "vm_radix_insert: key <vm_pindex_t> is already present".
