Hello,
I'm using linux3.3 and recently while building busybox for a new command, found
the BB uses linux kernel headers.
So I looked up the internet and did 'make headers_install ARCH=..
CROSS_COMPILE=.. INSTALL_HDR_PATH=..'.
Then I used the new header files instead of files under
sparc-snake-l
Hey Guys,
This commit seems to be needed to fixed up based on what the btrfs
developers, are stating on their wiki.
Other then the TODO list, which we can discuss here, is there any
other parts of this patch that need to
be rewritten, it's merged as of now but I can recreate new patches if
needed

You *do* realize that the btrfs maintainers haven't been banned from
anyplace, and have enough name recognition that if they wan
I agree with Valdis. This is how it works.

Each filesystem has its own use-case. Like XFS is for big data, btrfs
with its COW and other features meets some specific use-cases like
facebook where they have a scenario(refer
http://lwn.net/Articles/591780/ ) where btrfs suites then perfectly.

Hey Guys,
This is a favor for the btrfs developers, one of my aunt's work's at

to a few storage engineers about features they would like to see in a
file system and it's tools. In
addition if you would like to ask them about how to improve btrfs too,
I can send anot

Sure, here's some more context.
I'm one of the developers of sysdig (www.sysdig.org), a tool that
captures system calls and uses them to offer advanced system monitoring.
One of the features that our diver offers is the tcpdump-derived concept
of "snaplen": when a system call with a buffer is c

You don't have a "number" from within the

What problem are you trying to solve here? There may be a better API for
your problem. So step back - what are

I'm looking for an efficient way to determine the type of an fd (file,
socket...) given its number, from a kernel module.
The closest thing I found by looking at the kernel sources is
sockfd_lookup(), which works but is limited to tellin

hi all:
I want to mmap a kernel memory area which sk_buf->data pointer
into userspace. I want to do this , because this way can reduce a copy
from kernel to userspace.
How to fix it? Or, which book or project can help me ?
Thank you.

Hi Sharief,
It would always be better if you can provide the details of things you
are doing and steps you have carried out until it failed.
But if I can guess it right you are trying to upgrade kernel on local
machine which is x86 based. The failure seems while trying to install
