Hi Roland
Thanks for rebasing utrace patch on 2.6.25-rc6. On applying your patch, I
executed ptrace tests on my ppc system. I found 4 failures and most of the
failures are due to ptrace (PTRACE_SINGLESTEP, child, NULL, NULL) call.
This call fails with -ENOSYS.
PASS: ptrace-on-job-control-stop
patches, it didn't
get applied when I build the kernel using "rpmbuild" command.
So could you please point us to latest utrace patches.
Thanks
