From a47afb0f9d794d525a372c8d69902147cc88222a Mon Sep 17 00:00:00 2001 From: Pavel Emelianov Date: Thu, 18 Oct 2007 23:39:46 -0700 Subject: pid namespaces: round up the API The set of functions process_session, task_session, process_group and task_pgrp is confusing, as the names can be mixed with each other when looking at the code for a long time. The proposals are to * equip the functions that return the integer with _nr suffix to represent that fact, * and to make all functions work with task (not process) by making the common prefix of the same name. For monotony the routines signal_session() and set_signal_session() are replaced with task_session_nr() and set_task_session(), especially since they are only used with the explicit task->signal dereference.
