Got me, I should have said hardly used.
Hi,
The kthread park/unpark facility is not used in the kernel, so
one would assume that it's made for kernel modules. This patch should
definitely help most modules.
Patch untested, at your own risks...

Hi,
I already sent this e-mail to Luc and on the pwc mailing list,
and got no answer. I'm trying again with the hope that this patch
would go in the kernel...
I have a Cisco VT Camera, and it was just collecting dust. I
decided to try connecting it to my Linux box at home

Hi Marcelo,
This patch adds wildcard support for the SIOCSIFNAME ioctl,
like what was done in 2.6.1. SIOCSIFNAME allow a user space tool to
change network interface names (such as nameif, ifrename, or ip link),
this patch allow those tools to specify a pattern, such as "eth%d" or

Hi Linus,
I've got a question... I would like where to send my driver
patches...
One month ago, I sent a small update for the orinoco_cs driver
and Wireless Extensions. I didn't put all the changes I had for
orinoco_cs because I believe in small incremental updates limite

Hi,
I've found a really convoluted bug in the IrDA stack (spend
the week chasing it). As it is not trivial, I would like you to check
and comment on my description and my fix.
My patch definitely fix the problem on the PC where I was
seeing it, and I can't crash it anymore

Hi Linus and Alan,
This is a totally trivial update of the Wireless Extensions
definition. It just adds a few more #define, so no troubles or pain
expected.
The patch attached applies cleanly to *both* 2.4.0-test12 and
2.2.18 (tested), and I would suggest including it in b
