78 * There are two system calls in regard to sigaction, sys_rt_sigaction
79 * and sys_sigaction. Internally the kernel uses the struct old_sigaction
80 * for the older sys_sigaction system call, and the kernel version of the
81 * struct sigaction for the newer sys_rt_sigaction.
82 *
83 * The uapi definition for struct sigaction has made a strange distinction
84 * between 31-bit and 64-bit in the past. For 64-bit the uapi structure
85 * looks like the kernel struct sigaction, but for 31-bit it used to
86 * look like the kernel struct old_sigaction. That practically made the
87 * structure unusable for either system call. To get around this problem
88 * the glibc always had its own definitions for the sigaction structures.
89 *
90 * The current struct sigaction uapi definition below is suitable for the
91 * sys_rt_sigaction system call only.
