From a89e9b8abf82725e4ac96100e07c8104dbe8a240 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 15 May 2019 10:11:09 -0500 Subject: signal: Remove the signal number and task parameters from force_sig_info force_sig_info always delivers to the current task and the signal parameter always matches info.si_signo. So remove those parameters to make it a simpler less error prone interface, and to make it clear that none of the callers are doing anything clever. This guarantees that force_sig_info will not grow any new buggy callers that attempt to call force_sig on a non-current task, or that pass an signal number that does not match info.si_signo.
