Hi,
I have been having problems using rename system call
on vfat file systems. I have looked at the kernel code
and tried everything I could do to figure out what
might be going wrong. As a last resort I thought you
might be able to help me.

Even though you do not define "that", most likely I agree.
Still, many intermediate steps are needed.
For a very large number of these steps the final API is irrelevant.

Your analogy is flawed.
You state that "the kernel is the equivalent of an application", when
compared to user-space application/library relationships.
The flaw in this analogy is, a library does 'require! and use'
routines provided by the application. The library provides methods
and services
On my system, flag problem and boot panic fixed

If I am using a sysctl directory when the relevant unregister_sysctl_table()
is called, the directory and parent directories will continue to exist. Fine.
However when I cd out of the dir, the directory does not disappear.
When/where do sysctl directories get collected ?

Why does Linux have a mktime routine fully coded in linux/time.h that
conflicts directly with the ANSI C standard library routine of the same
name? It breaks a couple things against libc5, including gcc 3.0. OK, you
don't care about libc5. It's still pretty weird. Wierd? Weird.

I agree with the device vote. Also, if the interface to the vlan devices
are similar enough to ethernet that the bonding driver can easily
incorperate them, then you can get bonded (a.k.a. redundant) trunks for
cheap. This would lead to linux becoming a more robust router in practice.

The problem is that the IRQ has to be cleared in kernel

It depends on device type. Good designed

I agree, the idea is to clear the IRQ in kernel space
and then deliver to user level programs interested

Two choices:
- Disallow shared interrupts for usermode drivers.
- Make the 'generic interrupt handler

GPL + LGPL gives you GPL so it doesnt help. You can combine it with the driver
or with the kernel but not with both together.

There are real differences between programs and interface definitions. At this

IRQ 9 shared between user space app and disk. IRQ arrives is disabled and
