Bug#447018: BUG: warning at kernel/cpu.c:51/unlock_cpu_hotplug() patch

[abridgett@smop.co.uk (Adrian Bridgett)]

Package: linux-2.6
Version: 2.6.18.dfsg.1-13etch3
Severity: minor

Hi,

We are getting loads of these:

Call Trace:
 [<ffffffff8025d000>] .text.lock.mutex+0x5/0x14
 [<ffffffff80293e27>] unlock_cpu_hotplug+0x3f/0x6c
 [<ffffffff8027d958>] sched_getaffinity+0x7e/0x93
 [<ffffffff8029c612>] compat_sys_sched_getaffinity+0x1d/0x4c
 [<ffffffff8025aa87>] sysenter_do_call+0x1b/0x67


There is a patch at: http://lkml.org/lkml/2007/2/16/4  which I've
confirmed is in 2.6.22.  The actual error isn't harmful, just
annoying/worrying!

It would be great if this "swap two lines" patch could be included in
the next etch release.

Thanks,

Adrian
