[patch] For getrusage's argstr in tapset
Hi, everyone
In [tapset->probe getrusage], argstr's "who" argument is printed as
"RUSAGE_BOTH" when its value is -2.
But "RUSAGE_BOTH" is not used in getrusage syscall due to the following
kernel source:
asmlinkage long sys_getrusage(int who, struct rusage __user *ru)
{
if (who != RUSAGE_SELF && who != RUSAGE_CHILDREN)
return -EINVAL;
return getrusage(current, who, ru);
}
So i want to remove RUSAGE_BOTH from _rusage_who_str.
Is there anyone knows why RUSAGE_BOTH is necessary, please tell me.
and if no objection, I will commit it.
