This is an interim solution, and a more general one is being worked
on. This solution doesn't break anything that doesn't ask for it

hold the map lock there, and might need the vnode lock for OBJT_VNODE

drops the map lock. Link the map entries to be freed into the freelist,

acquire vnode lock for OBJT_VNODE object after map lock is dropped.
Because we have the busy page(s) in the object, sleeping there would
result in deadlock with vnode resize. Try to get lock without sleeping,
and, if the attempt failed, drop the state, lock the vnode, and restart
the fault handler from the start with already locked vnode.
Because the vnode_pager_lock() function is inlined in vm_fault(),
axe it.

o Put the start and end of the partition in the XML configuration.
The start and end are the LBAs of the first and last sector
(resp.) of the partition. They are currently identical to the
offset and size attributes, which describe the partition as an
offset and size in bytes, but may not in the future. The start
and end will be used for the logical partition boundaries and
may include metadata. The offset and size will always represent
the useful storage space within the partition. Typically these
two notions are the same, but for logical partitions in an

The file local functions ipsec4_setspidx_inpcb() and

in r186528. Rename to ipsec_setspidx_inpcb() and remove the

Remove one copy and merge in the factored out code from
