kprobes


Hi, mavens:
I'm a commoner who're interested in learning linux kernel. Lately I followed the article on ibm (... l-kprobes.html) to learn how to use kprobe to debug kernel, but I encountered a probelm after 'patch'ing files to kernel source. I downloaded files first from ibm Kernel Probes project (... kprobes-dprobes-2.6.8-rc1-full.patch.bz2).
And then patch it to my kernel source version 2.6.8, previously downloaded from kernel.org.
Then I tried to compile kernel, but it issued error as followed:
[BTW, when I patch kernel source, there's messenges appearing like "can't patch to the kernel .... in put line xxx", seemly looks like it(kernel and patch version) doesn't match with each other]
==========error printed on console==========BEG
arch/i386/kernel/traps.c:29: linux/kprobes.h:No such files or directory
arch/i386/kernel/traps.c:46: asm/kwatch.h:No such files or directory
arch/i386/kernel/traps.c:29: In function "do_general_protection"
...
==========error printed on console==========END
seemly I miss lots of files after typing command "make". Where did I do it wrong? Is it because the patch version incorrect? For I found out that the kprobes patch file I download from ibm website, seemly it's for kernel version 2.6.8-rc1 [from the file name I suppose]; however, I can't find any rc1 version on kernel.org. What should I do in order to enable this option? Or are there any better suggestion?
I appreciate it, sincerely.
Jason
p.s: sorry, the messenge tell me that I can't post the url, therefore, I only left page and file name as keywords.

must be that patch is designated rc1
that is it's for 2.6.8-rc1
which is the first release cantidate (cvs snapshot) from the 2.6.8 line
this would be quite a bit different from the final release 2.6.8
trouble is i have no idea where you can get these releases
(it was most likely a patch to 2.6.7)
i see on the board
Linux 2.6.8-rc1
From: Linus Torvalds

hope you can find that

after several check, i got a reply from ibm, now that i can use kernel version 2.6.9 to use kprobe.
thanks your help, sincerely. [p.s.,:i tried to get from kernel.org for version 2.6.8rc1 with patch from ibm kprobe, but it still failed! Therefore, I replace 2.6.8 with version 2.6.9, and now it works.]
