*/
/* Each syscall returns the calls parameters. In addition, the following
* variables are set:
*
* name - generally the syscall name minus the "sys_".
*
* argstr - a string containing the decoded args in an easy-to-read format.
* It doesn't need to contain everything, but should have all the
* important args. Set in entry probes only. Values enclosed in
* square brackets are user-space pointers. Values in curly
* braces are decoded structs.
*
* retstr - a string containing the return value in an easy-to-read format.
* Set in return probes only.

# clone ______________________________________________________
#
# The sys_clone() call was in arch-specific code (sometimes assembly
# code), especially in older kernels. Its args varied dramatically,
# from full args to getting nothing but registers. To get around this,
# we'll just probe do_fork(). The fork()/vfork()/clone() syscalls are
# just wrappers around do_fork(). We'll reject all probe hits that
# aren't really clone syscalls (such as calls to sys_fork(),
# sys_vfork(), and the kernel's internal use of do_fork()). Kernel
# commit 3033f14ab78c32 renamed 'do_fork' to '_do_fork'.
#
# For ia64, this is complicated by the fact that it has a clone2
# syscall.
#
# kernels < 3.8.0:
# long do_fork(unsigned long clone_flags,
# unsigned long stack_start,
# struct pt_regs *regs,
# unsigned long stack_size,
# int __user *parent_tidptr,
# int __user *child_tidptr)
#
# kernels >= 3.8.0:
