From c046e2c693c770153acb568e56c0c41cce9c91e2 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sun, 15 Apr 2018 21:10:23 -0500 Subject: signal/nios2: Use force_sig_fault where appropriate Filling in struct siginfo before calling force_sig_info a tedious and error prone process, where once in a great while the wrong fields are filled out, and siginfo has been inconsistently cleared. Simplify this process by using the helper force_sig_fault. Which takes as a parameters all of the information it needs, ensures all of the fiddly bits of filling in struct siginfo are done properly and then calls force_sig_info. In short about a 5 line reduction in code for every time force_sig_info is called, which makes the calling function clearer.
