sys/vm vm_contig.c
Log:
Correct a long-standing race condition in vm_contig_launder() that could
result in a panic "vm_page_cache: caching a dirty page, ...": Access to the
page must be restricted or removed before calling vm_page_cache(). This
race condition is identical in nature to that which was addressed by
vm_pageout.c's revision 1.251 and vm_page.c's revision 1.275.
