[PATCH] [RFC] remove ext3 inode from orphan list when link and unlink race
I think this is better than the original idea of trying to handle the race;
I've seen that the orphan inode list can get corrupted, but there may well

This is a full replacement queue for the high resolution timer / dynamic

This version includes the following improvements:
- Seperate clockevents management of devices and users
- Provide a generic tick managament infrastructure, which makes use

Add a flag so we can prevent the irq balancing of an interrupt. Move
the bits, so we have room for more :)
Necessary for the ability to setup clocksources more flexible (e.g. use
the different HPET channels per CPU)

For CONFIG_NO_HZ we need to calculate the next timer wheel event based
on a given jiffie value. Extend the existing code to allow the extra
'now' argument. Provide a compability function for the existing
implementations to call the function with now ==
From: Thomas Gleixner [EMAIL PROTECTED]
When searching for the next pending timer in the timer wheel we
need to take the cascade into account. The current code has several
problems:
1. it looks into the previous cascade
2. it ignores a pending cascade
3. it ignores multiple cascades

This is a preperatory patch for highres/dyntick:
- replace the big #ifdef ARCH_APICTIMER_STOPS_ON_C3 hackery by functions
- remove the double switch in the power verify function (in the worst case
we switched ipi to apic and 20usec later apic to ipi)

Allow early access to the power management timer by exposing the
verified read function and providing a helper function which checks the
pmtmr_ioport variable and returns either the pm timer readout or 0 in
case the pm timer is not available.

Add /proc/timer_stats support: debugging feature to profile timer
expiration. Both the starting site, process/PID and the expiration
function is captured. This allows the quick identification of timer
