- Subject: Systemtap and weak symbols
I just tried the new kernel (v2.6.14-rc5-mm2) and found out that some
the system calls on the latest kernel becomes weak symbols. Systemtap
can't resolve the weak symbol function
cat /proc/kallsyms | grep sys_chown16
c01395e0 W sys_chown16
stap -e 'probe kernel.function("sys_chown16"){}'
emantic error: no match for probe point
while: resolving probe point kernel.function("sys_chown16")
Pass 2: analysis failed. Try again with '-v' (verbose) option.
Is this a systemtap bug?
Hien.
