From 5acac1be499d979e3aa463ea73a498888faefcbe Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Wed, 4 Dec 2013 18:28:20 +0100 Subject: tick: Rename tick_check_idle() to tick_irq_enter() This makes the code more symetric against the existing tick functions called on irq exit: tick_irq_exit() and tick_nohz_irq_exit(). These function are also symetric as they mirror each other's action: we start to account idle time on irq exit and we stop this accounting on irq entry. Also the tick is stopped on irq exit and timekeeping catches up with the tickless time elapsed until we reach irq entry. This rename was suggested by Peter Zijlstra a long while ago but it got forgotten in the mass. Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Alex Shi Cc: Steven Rostedt Cc: Paul E.
