in two ways
1) make mrproper
2) make O=$HOME/btc mrproper

said ,things will be clear.

Hi,
For a specified directory, we can go through it when the kernel
parsing path, though we can not read it. Actually, parsing path also
need read the directory file. So, how does the kernel distinguish
between these two permission?

Hi all,
For exercise purposes I have coded a device driver that shares an IRQ line
with other devices.
In the code from the book I am reading (Cooperstein's), the interrupt handler
returns IRQ_NONE. Close to that code there's the comment "We're just
observing".
What I don't understand is why

Hey Mohit,
This is a feature of GCC (I don't know if it is a part of the standard).
Here's the link from the GCC manual:

Hi,
I was going through a tutorial given here
http://www.kroah.com/linux/talks/ols_2005_driver_tutorial/mgp00010.html
I could not understand what did it means to bind to device as it is shown in
this function on above link.

Its not that I had not searched it did search but I had searched typedef and

What to be searched is not that obvious when some one is not clear.

Now when I try to cross compile cairo, configure gives the following error:
