From 07354eb1a74d1e1ece29f8bafe0b46e8c77a95ef Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 25 Jul 2009 17:50:36 +0200 Subject: locking, printk: Annotate logbuf_lock as raw The logbuf_lock 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.
