-systemtap: Fixed probe syscall.sendfile failure
-
-compat_sendfile syscall is unavailable in kernels starting version 3.8.
-Hence systemtap scripts like 'probe syscall.* { if (target()==pid()) log(name." ".argstr) }' fail.
-This problem is solved by marking __syscall.compat_sendfile as optional in tapset/linux/syscalls2.stp
