* 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.
