From ec74e9205e064af6a7076faabe649335acc78b69 Mon Sep 17 00:00:00 2001 From: Eric W. Biederman Date: Thu, 7 Feb 2019 10:05:12 -0600 Subject: signal/unicore32: Remove tsk parameter from __do_user_fault The __do_user_fault function is always called with tsk == current. Make that obvious by removing the tsk parameter. This makes it clear that __do_user_fault calls force_sig_fault on the current task. Signed-off-by: "Eric W.
