So the idea has already been announced. It is better to send a patch
with the suggested "fix" for list stuff. No? :)
Thanks

This functions are helpers for the generic link layers(L2) params setup.
For example:
/**
* ether_setup - setup Ethernet network device
* @dev: network device
* Fill in the fields of the device structure with Ethernet-generic values.
*/
void ether_setup(struct net_device *dev)
{
dev->
There are many good examples in drivers/net.
drivers/net/pci-skeleton.c for example. I think that it is a not big
problem to compare the text from the link with the current state of
the device drivers.

Right,
task list traversal must be performed under a tasklist_lock.

You can start reading the source code.

I think that you could _try_ to ask in netfilter-devel and netdev
about this.

Yeah, schedule() (and __sched prefixed) function call needed when we are
waiting for some events. It would de wasteful to lose CPU cycles while
checking condition what we are waiting for. So, instead we can just to tell

Recently there are too many messages not related to the Linux kernel topic.
And this is a bad sign :/

I think that you can use one of the functions from include/linux/pid.h like
this one:
struct pid *find_pid_ns(int nr, struct pid_namespace *ns)
292{
293struct hlist_node *elem;
294struct upid *pnr;
295

Hello dear all!
Suppose, we have the following pseudo code:
spin_lock(&some_lock);
some_func();
spin_unlock(&some_lock);
some_fun()
{
.
wake_up_interruptibe_sync(&wait_queue);
}
Is this correct behavior or not?
This is a call chain:
wake_up_interruptible_sync ---> wake_up_s

Hi dear list.
I encountered the following problem: from time to time I see a delay when
booting the kernel (~30s). It doesn't happen regularly.
I would like to ask you for advice as to what may be the reason for such
behavior?
Latter on I can attach kernel boot log and config.

Good times.
Look at the code. What do you think will be the result?
#include
#include
#include
void trap1(int sig)
{
fprintf(stderr, "signal\n");
}
int main()
{
int stat;
signal(SIGUSR1, trap1);
if (fork()) {
pause();

I have a copy. It's well, but too big)
Recently was published book about TCP/IP stack implementation in Linux:
http://www.amazon.com/Architecture-Design-Implementation-Linux-Practitioners/dp/0470147733/ref=sr_1_3?ie=UTF8&s=books&qid=1231089656&sr=8-3
I think that the book should be good.

Hi!
The function calibrate_delay() from init/main.c comtains the following line:
printk(KERN_CONT "%lu.%02lu BogoMIPS (lpj=%lu)\n",
loops_per_jiffy/(50/HZ),
(loops_per_jiffy/(5000/HZ)) % 100, loops_per_jiffy);
Please explain how bogoMIPS is computed. Why loops_per_jiff
