mmap'ed /dev/poll patches for Linux-2.2.14.
------------------------------------------

patch-2.2.14-devpoll	Includes the implementation of a /dev/poll that
			can be memory mapped to share the table of
			struct pollfd * between the user process and the
			kernel.  This avoids all copies normally associated
			with select() or poll().  The device supports three
			different ioctl() calls: DP_ALLOC, DP_FREE, and
			DP_POLL.  Look at devpoll-sample.c to see how they
			are used.  Applies against Linux kernel v2.2.14.

			Create the device in /dev with
			mknod poll c 10 125

thttpd-2.15-devpoll.diff
			Supports a memory mapped /dev/poll instead of
			the poll system call.  Avoids all poll related
			user space to kernel space copies and vice versa.
			Applies against the thttpd-2.15 distribution.

devpoll-sample.c	A userland program that uses /dev/poll.

Hinting system patches for Linux-2.2.9.
---------------------------------------

hintvsnohint.ps		graph from a benchmark with httperf-0.6 and
			thttpd-2.04 over loopback on a 450 MHz 4-waz Xeon.

patch-2.3.15-hinting	adds hinting to select()/poll(). At the moment only
			network sockets use hinting.  It would be easy to
			extent that to different subsystems.

patch-2.2.9-ac4-niels	support for large filedescriptor sets, taken from
			2.2.7-ac4.

patch-2.2.9-hinting	adds hinting to select()/poll(). At the moment only
			network sockets use hinting.  It would be easy to
			extent that to different subsystems.
			Apply patch-2.2.9-ac4-niels first.

patch-2.2.9-np-bitmap	two level bitmap structure for finding a new file
			descriptor in open.  Results in faster file
			descriptor allocation for processes with many open
			fds.
