Hello Lel;

This is list is concerned with NDT development; you should inquire about kernel patching on the web10g-user list:

https://lists.psc.edu/mailman/listinfo/web10g-user

FWIW, based on your example, it looks like you may be trying to apply the 3.11 web10g patches to the 3.0.11 kernel source (vs. 3.11.x), so that will likely never work.  Make sure you are grabbing the latest kernel release that matches the number and version of the web10g patches you are targeting.

Best of luck,

-tt

Hello everyone, I am an absolute newbie to patching and kernel
implementations. I am trying to patch the web10g patch to a linux kernel but
have had no luck. I have downloaded the kernel images from kernel.org:

https://www.kernel.org/pub/linux/kernel/v3.x/

I have miserably tried to patch the images 3.17, 3.14, and 3.11, all of them
getting errors on many hunks, for example:

This same thing happens to all the above versions. Has someone been able to
patch a kernel with a diff that already has the tcp_estats_nl kernel module?

thank you!
