Dear Subscribers,
After browsing the web for several hours I turn to you to get an answer.
As stated in LDD3 p.436 the function get_user_pages can return fewer
pages than requested (have already seen this during testing).

Allow me to share my thought here..

are codes like the following which I can not understand:

slab_bufctl(slabp)[objnr] = slabp-free;
slabp-free = objnr;
slabp-inuse--;
and slab_bufctl(slabp) is (kmem_bufctl_t *)(slabp + 1).

Ok. So I've successfully compiled a kernel without any errors into .rpm
format. When I install the kernel I have no errors. However, when I type
mkinitrd I get the following:
Cannot determine dependencies of module adpahci. Is modules.dep up to date?
I ensured that the module was in the

Hi...
I'd like to know if there's a way to set a system-global flag in user
mode that can be read in kernel mode. Specifically, I'd like to know
if a NAPI poll function is being executed during a system call that I
wrote, so the idea is to set the flag before the system call is
invoked, clear
Hi...
I don't do any special commands just:
depmod
mkinitrd
Is that my problem?
yes, I believe so. Please read the manual more carefully. Hint for
mkinitrd:
mkinitrd image you want to build kernel version that you build the
initrd against
Hint for depmod:
depmod kernel version that
Hello,
I'm pretty new to kernel development and would like to setup a ideal
dev system for playing
around. I've read most of the documents posted on kernelnewbies and I
specifically would
like to compile many kernels and play around with them.
I'd like to know what an
No, because that would only turn the flag on inside the kernel. I need
it on before the system call starts executing.
My quick'n'dirty hack is to user the FPU control word. It is accessible
from user mode, very cheap to read and write, globally enforced, and
doesn't seem to be causing any
TCP checksum may actually be computed in hardware, so that the value you
see in the packet may not be the final checksum value.
Which NIC are you using? You can use ethtool to check whether it has TCP
offload capabilities.

I sure was.
