That would be fine with me.  The nodes are readable only by user, which
seems sufficient to me.  But I certainly don't object to the stronger check
there.  I didn't put too much thought into /proc/pid/syscall, it's just
there to demonstrate and test the internal task_current_syscall() call.


Thanks,
Roland
