New Revision: 300596
URL: https://svnweb.freebsd.org/changeset/base/300596
Log:
In vm_page_alloc_contig(), on vm_page_insert() failure, mark each
freed page as VPO_UNMANAGED. Otherwise vm_pge_free_toq() insists on
owning the page lock.
Previously, VPO_UNMANAGED was only set up to the last processed page.
