/* Each syscall returns the calls parameters. In addition, the following

*
* 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.
*
* retstr - a string containing the return value in an easy-to-read format.
* Set in return probes only.
