Hi,
Thanks.
I have put in the kernel patch code to use the utrace interface. It is

I patched Ubuntu 2.6.24.3 with utrace and perfmon2. Moreover, I unset
"Legacy ptrace system call interface (PTRACE)". I get the following compile
error:
CC perfmon/perfmon_syscalls.o
perfmon/perfmon_syscalls.c: In function 'pfm_get_task':
perfmon/perfmon_syscalls.c:159: error: implicit declaration of function
'ptrace_check_attach'
make[1]: *** [perfmon/perfmon_syscalls.o] Error 1
make: *** [perfmon] Error 2
Also, I could not find any "#define CONFIG_UTRACE" in the perfmon2-patch. Is
utrace supported by the 2.6.24 patch, or only 2.6.26?
Cheers,
Andrej
