can you tell me why??

Hello,

I'm trying to generate a patch for use with ksplice on Gentoo.
I have the running kernel sources and new updated kernel sources.

I run diff -r -u newlinux oldlinux > diff which gets me the patch.

When I run ksplice-create --patch=diff --config=. -j 5 /tmp/oldlinux
(. contains System.map, a build symlink linked to /tmp/oldlinux, and .config)

it compiles fine for most of the file but near the end there are a lot of rejects.

What am I doing wrong?

Hi,

I'm trying to roll together a patch against the official openvz kernel source (which bases from the RHEL 6 kernel source).

Here is the errors I get reported back:

/tmp/ksplice-tmp-SwNsuW/kmodsrc/ksplice.c: In function âapply_updateâ:

Is this supposed to work with CentOS 6?

because in kmodsrc/ksplice.c 2766 line,
(unsigned long)task_thread_info(t)-> restart_block.fn
the member restart_block only exists in 3.* kernel, it was removed in 4.* kernel .
