From 2e1661d2673667d886cd40ad9f414cb6db48d8da Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 23 May 2019 11:04:24 -0500 Subject: signal: Remove the task parameter from force_sig_fault As synchronous exceptions really only make sense against the current task (otherwise how are you synchronous) remove the task parameter from from force_sig_fault to make it explicit that is what is going on. The two known exceptions that deliver a synchronous exception to a stopped ptraced task have already been changed to force_sig_fault_to_task. The callers have been changed with the following emacs regular expression (with obvious variations on the architectures that take more arguments) to avoid typos: force_sig_fault[(]\([^,]+\)[,]\([^,]+\)[,]\([^,]+\)[,]\W+current[)] -> force_sig_fault(\1,\2,\3) Signed-off-by: "Eric W.
