[vbox-dev] [PATCH] Fix FreeBSD panic: mutex vm page queue free mutex not owned and PG_UNMANAGED compile problem

Fri, 02 Dec 2011 03:56:27 -0800

The first hunk of the patch fixes a compile problem on FreeBSD 10-CURRENT: 

Remove explicit initialization of m->flags and m->oflags because per
default vm_phys_alloc_contig() already initializes the page as unmanaged. 
Chase move of PG_UNMANAGED flag from m->flags to m->oflags and renaming
to VPO_UNMANAGED for an additional assert.
The following hunks fix the following panic on FreeBSD 10-CURRENT hosts:
panic: mutex vm page queue free mutex not owned at /root/deviant2/sys/vm/vm_phys.c:882
