SVN rev 202979 on 2010-01-25 18:15:10Z by jhb
MFC 194607:
Implement a mechanism within vm_phys_alloc_contig() to defer all necessary
calls to vdrop() until after the free page queues lock is released. This
eliminates repeatedly releasing and reacquiring the free page queues lock
each time the last cached page is reclaimed from a vnode-backed object.
