# What's in this kernel?
# INCLUDED:
# xfs (13 Feb 2002 CVS)
# read-latency2.patch from http://www.zipworld.com.au/~akpm/linux/2.4/2.4.18-pre9/
# (improves multiple disk read/write IO performance)
# fastpte
# (enables an option to do fast scanning of the page tables)
# preempt-kernel-rml-2.4.17-3 from http://www.tech9.net/rml/linux/
# (preemptible kernel)
# loopback device deadlock fixes from akpm
# ADDED in 2.4.17-r5:
# acpi-20020214-2.4.17.diff.gz from http://sourceforge.net/projects/acpi
# This patch should close bug #689 which was sent upstream.
# REMOVED from 2.4.17-r5:
# ide.2.4.17.02072002.patch from http://www.linuxdiskcert.org/
# (revamped IDE code; this closes bug #690; we'll add it back as soon as the
# confirmed with author completion error is fixed (probably in the next release))
