From c467ea763fd5d8795b7d1b5a78eb94b6ad8f66ad Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 4 Mar 2015 18:06:33 +0100 Subject: context_tracking: Rename context symbols to prepare for transition state Current context tracking symbols are designed to express living state. As such they are prefixed with "IN_": IN_USER, IN_KERNEL. Now we are going to use these symbols to also express state transitions such as context_tracking_enter(IN_USER) or context_tracking_exit(IN_USER). But while the "IN_" prefix works well to express entering a context, it's confusing to depict a context exit: context_tracking_exit(IN_USER) could mean two things: 1) We are exiting the current context to enter user context. 2) We are exiting the user context We want 2) but the reviewer may be confused and understand 1) So lets disambiguate these symbols and rename them to CONTEXT_USER and CONTEXT_KERNEL.
