The directory /usr/include/linux is a real one containing lots of header

RedHat made this reconstruction, but I think it's better to keep it there.

Subject: Re: config for pre-built kernel (RH 6.2)
i believe the .config file (note the "." meaning a hidden file) is in
/usr/src/linux already but I could be wrong.
In theory when issuing a 'make xconfig' it should set all the features
to the same settings as they are set to in the .config file. In that way
everything in your current kernel is already selected as it should be.

Subject: Seeking clarification on linux's handling of inodes
Date: 1 Dec 2000 02:50:18 GMT
I'm looking at the sources in fs/ and it looks like linux's
high-level fs interface uses a unified inode type for all fs's.
This made me curious, because some fs's don't use inodes (eg,
msdos's FAT fs), and then I saw that there's an "msdos" field
in a union in "struct inode" and explored further. Does linux
create inodes on the fly after mounting a filesystem that does
not use inodes? If so, where are these inodes stored?
If I sound confused, it's because I am. This is the first
time I've looked at linux's fs code, and it flies in the face
of how I was taught Unix fs's work in college many moons ago.
(Not that I think that's BAD .. I'm just trying to understand
it, is all.) Is there some source of documentation (online
or wood pulp) that describes how to port or implement a fs for
linux?
Thanks muchly,

Only queued SIGIO fills in SI_SIGINFO in 2.2 and 2.4. You get queued SIGIO by
setting a realtime signal (>SIGRTMIN) using the F_SETSIG fcntl on a
socket or tty file descriptor. Then set SA_SIGINFO on the realtime signal
handler.
When the signal queue should fill up the kernel falls back to send
an unqueued SIGIO signal. You should handle that case and collect
all outstanding events using poll() then.
In 2.2 only si_fd is filled and si_band/si_code do not conform to Posix
and should not be depended on (2.4 fixes them to be POSIX/Single Unix
compliant)
Also all released 2.2 kernels have an annoying bug that makes queued
SIGIO fall back to unqueued SIGIO in some cases even the queue is not
full (will hopefully be fixed in 2.2.19). 2.4 doesn't have that problem.

Yes, you're right. I was not considering the standard, but rather some
implementation thereof.
However, I was merely commenting on a specific example and what it was
supposed to mean.

RedHat ships a set of config files in the "/usr/src/linux/configs"
directory.
The pre-installed kernels are usually i386 kernels, you then have the
choice between
kernel-2.2.14-i386-BOOT.config
kernel-2.2.14-i386.config
kernel-2.2.14-i386-smp.config
You can skip the "BOOT" thing, it's only used during installation (if
used at all), this leaves the uniprocessor and smp configs.
Copy the relevant file to /usr/src/linux/.config, do a "make oldconfig",
then "make dep bzImage modules".

I though i would embaress this list by being to obvious :-) (or rather
see at the bottom).
Also i see so many news messages i wish there was a way to
speed read them and still manage to comprehend whats important.
Anyway to make things more explicit then.
A constructor (in this case a C++ constructor, but i suppose the problem
applies
to other global initializers as well) is the member function that gets
called
when an object is first created.
A global object (or i suppose a global variable) is defined in
the global section of a program (outside of any function).
So a global constructor is (in my case) the constructor of a global
object.
And my problem is that it doesn't get called.
To explain why this is a problem: *It is supposed to get called*.
Further studies with gdb (the gnu debugger) reveals that the objects
vtbl (virtual function table) isn't initialized either.
I seem to remember i had this problem before then it was a
global variable beeing initialized like this
int a=somefunction();
at that time i just gave up and reworked the whole program.
Now, i know that there is a lib libelf which lets you tinker
whith shared objects. But i don't know anything about it.
But what i do know is that there is a lot of knowledgeable people
on this list. Maybe even those who have constructed the ELF system
in linux.
But i feared that they like me read to many news messages and that
they, like me, skip those that are to wordy and doesn't come to the
point.
So my idea was that whoever knew the answer would also understand the
question
and would also not skip the message.
