#What's in this kernel?
#======================
# EXISTING patches:
# xfs (26 Jan 2002 CVS)
# read-latency-2 from akpm (improves multiple disk read/write IO performance)
# fastpte (enables an option to do fast scanning of the page tables)
# irqrate-a1 (optimizes irq handling, no more ksoftirqd and eliminates irq storms on servers)
# ide (from http://www.linuxdiskcert.org, patch ide.2.4.17.01192002.patch) ide updates, performance improvements
# note: enable "Taskfile" options in kernel config
# preempt-2.4.17-r1 (preemptible kernel)
# loopback device deadlock fixes from akpm
# NEW in 2.4.17-r3:
# acpi-20011205 (ACPI support, new-style power management)
# REMOVED from 2.4.17-r3:
# readahead patch from akpm (really slowed things down; was mistakenly recommended to me before it was ready)
