a50b705403 Use VM_ALLOC_NOBUSY to eliminate vm_page_wakeup() calls and the acquisition 
and release of the global page queues lock required to make the call.

Remove GIANT_REQUIRED from vm_hold_free_pages().  All of its VM operations
are properly synchronized.

ae1e5c5d8d Move from using the socket reference count to the file reference 
count to prevent sockets from being garbage collected during
socket-specific system calls.  This is the same approach used in
most VFS-specific system calls, as well as generic file descriptor
system calls such as read() and write().

To do this, add a utility function getsock(), which is logically
identical to getvnode() used for the same purpose in VFS.  Unlike
fgetsock(), it returns with the file reference count elevated, but
no bump of the socket reference count.  Replace matching calls to
fputsock() with fdrop().

This change is made to all socket system calls other than
sendfile() and accept(), but the approach should be applicable to
those system calls also.

This shaves about four mutex operations off of each of these
system calls, including send() and recv() variants, adding about
1% to pps on minimal UDP packets for UP using netblast, and 4% on
SMP.

c999732b45 Log the actual number of bytes sent on the wire to /var/log/ftpd 
instead of the disk size of the file sent.   Since the log file
is intended to provide data for anonymous ftp traffic accounting,
the disk size of the file isn't really informative in this case.

b792bebeea Move the buffer method vector (buf->b_op) to the bufobj. 
Extend it with a strategy method.

Add bufstrategy() which do the usual VOP_SPECSTRATEGY/VOP_STRATEGY
song and dance.

Rename ibwrite to bufwrite().

Move the two NFS buf_ops to more sensible places, add bufstrategy
to them.

Add inlines for bwrite() and bstrategy() which calls through
buf->b_bufobj->b_ops->b_{write,strategy}().

Replace almost all VOP_STRATEGY()/VOP_SPECSTRATEGY() calls with bstrategy().

b6b3698c8e Fix a panic discovered with some apache2 configure test (that seemed to 
trigger a socket creation race some some kind). Checking for non-NULL socket
and credential is not a bad idea anyway. Unfortunatly too late for the
release.

e5526e6aa5 Acquire the vm object lock before rather than after calling 
vm_page_sleep_if_busy().  (The motivation being to transition
synchronization of the vm_page's PG_BUSY flag from the global page queues
lock to the per-object lock.)
