From ee30a7b2fc072f139dac44826860d2c1f422137c Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 25 Jul 2009 18:56:56 +0200 Subject: locking, sched: Annotate thread_group_cputimer as raw The thread_group_cputimer lock can be taken in atomic context and therefore cannot be preempted on -rt - annotate it. In mainline this change documents the low level nature of the lock - otherwise there's no functional difference. Lockdep and Sparse checking will work as usual.
