From 6720a305df74ca30bcc10fc316881641b6ff0c80 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 23 Jun 2016 12:11:17 -0700 Subject: locking: avoid passing around 'thread_info' in mutex debugging code None of the code actually wants a thread_info, it all wants a task_struct, and it's just converting back and forth between the two ("ti->task" to get the task_struct from the thread_info, and "task_thread_info(task)" to go the other way). No semantic change.
