Don Lewis 3a140162b4 Fix up locking problems in fifo_open() and fifo_close():
Sleep on the vnode interlock while waiting for another
	caller to increment fi_readers or fi_writers.  Hold the
	vnode interlock while incrementing fi_readers or fi_writers
	to prevent a wakeup from being missed.

	Only access fi_readers and fi_writers while holding the vnode
	lock.  Previously fifo_close() decremented their values without
	holding a lock.

	Move resource deallocation from fifo_close() to fifo_inactive(),
	which allows the VOP_CLOSE() call in the error return path in
	fifo_open() to be removed.  Fifo_open() was calling VOP_CLOSE()
	with the vnode lock held, in violation the current vnode locking
	API.  Also the way fifo_close() used vrefcnt() to decide whether
	to deallocate resources was bogus according to comments in the
	vrefcnt() implementation.

This is the top level of the FreeBSD source directory.  This file
was last revised on:
$FreeBSD$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel, the kernel-modules and the contents of /etc.  The
``buildkernel'' and ``installkernel'' targets build and install
the kernel and the modules (see below).  Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process, documentation
for which can be found at:
   http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
And in the config(8) man page.
Note: If you want to build and install the kernel with the
``buildkernel'' and ``installkernel'' targets, you might need to build
world before.  More information is available in the handbook.

The sample kernel configuration files reside in the sys/<arch>/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file NOTES contains entries and documentation for all possible
devices, not just those commonly used.  It is the successor of the ancient
LINT file, but in contrast to LINT, it is not buildable as a kernel but a
pure reference and documentation file.
