Modified Files:
	syssrc/sys/kern: vfs_subr.c

Log Message:
in vinvalbuf(), vtruncbuf() and vflushbuf(), don't skip calling
VOP_PUTPAGES() just because the vnode has no pages.  layered filesystems
will want to pass these calls on through to the underlying filesystem,
and non-layered filesystems may need to remove the vnode from the
syncer queues.  fix up MP locking and add some locking assertions.
fixes PRs 12284 and 14640.
