commit 9a59aed914fbe25e159b2a60a97693f14b24ddf3
Author: Przemyslaw Pawelczyk <przemyslaw@pawelczyk.it>
Date:   Sat Oct 10 12:14:54 2009 +0200

    Add the .call modifier to syscall entry probes.
    
    Inline functions do not have an indentifiable return point and require
    kernel built using VTA-enabled gcc to get tracking of variables. OTOH
    syscall functions are very rarely inlined (depending on the compiler
    mood), therefore filtering probes to include only non-inlined functions
    ensures consistent behavior between different kernels.
    
    This removes the problem of inaccessible variables in inlined syscalls
    that is described in comments #6-9 to PR5890 and gives us the status quo
    w.r.t. syscall probing, because before the commit solving PR10572
    (b7478964) inline instances were masked anyway by non-inline ones.
    
    You can check whether you have inlined syscalls using following command:
    $ stap -l 'kernel.function("sys_*"),kernel.function("compat_sys_*")' \
                          2>&1 -vvv | awk '/^selected inline/{print $5}'
    
    * tapset/syscalls.stp: Add .call to all entry probes.
    * tapset/syscalls2.stp: Ditto.
