[PATCH] [9/23] PRINTK: Use stable variable to dump kmsg buffer
kmsg_dump takes care to sample the global variables inside a spinlock, but then goes on to use the same variables outside the spinlock region too. Use the correct variable. This will make the race window smaller. Found by gcc 4.6's new warnings. Signed-off-by: Andi Kleen <ak(a)linux.intel.com> --- kern... 10 Jun 2010 07:47

I haven't tried to fix all occurrences, but at least the major ones for my configuration. If someone is interested more work would be possible on this. ... 10 Jun 2010 07:47
