Re: Board and OS suggestion

[Kernel Apprentice]

I'm a Kernel noob myself, but you do realise this is the mailing list 
for people that are trying to get into Linux Kernel Development and thus 
completely unrelated to any other Operating Systems?
Secure Os means something like tiny os available 
http://www.tinyos.net/ or SEL4 http://ssrg.nicta.com/projects/seL4/


Any board has wifi connectivity?

`
on disk format is little-endian.

have a look at https://btrfs.wiki.kernel.org/index.php/Main_Page for
more information.

What do you mean with a secure OS? What do you need it to do?

(Also, is this related to the kernel?)

Re: Btrfs Issues

[Manish Katiyar]

Is your btrfs on an external drive and did you remove the drive and then
try to unmount the filesystem ?

Thanks -

Btrfs Issues

I am wondering if this is a bug or just a common issue.

It did then, too (unless I'm missing something)

linux$  git branch
* (detached from v2.6.12)
  master

from v2.6.12

void cdev_init(struct cdev *cdev, struct file_operations *fops)
{
memset(cdev, 0, sizeof *cdev);
INIT_LIST_HEAD(&cdev->list);
cdev->kobj.ktype = &ktype_cdev_default;
kobject_init(&cdev->kobj);
cdev->ops = fops;
}

Being able to access the machine monitor is very useful at times.  It
lets you look at registers, memory, hardware, etc.  I also appreciate
being able to quickly boot a kernel with the -kernel option.

If you are working on something unrelated to real-hardware then using
a virtual machine can help you, like not having frequent reboots
of your physical machine maybe you've only one development machine
then you can try and attach gdb to the virtual machine
from your host machine.

If however you've a real hardware then using a real machine would be better.

You don't really need to append the addresses in this step. Using --to
and --cc with "git send-email" is sufficient.

I don't think we want to automate the last step. Kernel coders are fast
learners and "confirmation" is quickly turned into automatically
pressing 'y' without thinking...

I have wondered about the same thing wrt get_maintainer.pl and git
send-email. You can of course script this somewhere else, but it seems
to me that a new switch to get_maintainer.pl creating a suitable would
be useful?

(Note that the copy/paste can be made easier by using the existing
switches: 
 scripts/get_maintainer.pl --nomultiline --separator ", --cc=" --file 
my/patched/file.c
but this can still be improved a lot)

No, it's not. But it could be convenient if you don't want to hurt your
machine.
