+ * There are two system calls in regard to sigaction, sys_rt_sigaction
+ * and sys_sigaction. Internally the kernel uses the struct old_sigaction
+ * for the older sys_sigaction system call, and the kernel version of the
+ * struct sigaction for the newer sys_rt_sigaction.
+ *
+ * The uapi definition for struct sigaction has made a strange distinction
+ * between 31-bit and 64-bit in the past. For 64-bit the uapi structure
+ * looks like the kernel struct sigaction, but for 31-bit it used to
+ * look like the kernel struct old_sigaction. That practically made the
+ * structure unusable for either system call. To get around this problem
+ * the glibc always had its own definitions for the sigaction structures.
+ *
+ * The current struct sigaction uapi definition below is suitable for the
+ * sys_rt_sigaction system call only.
