Message-ID: <20080724115121.GA28269@parisc-linux.org> Date: Thu, 24 Jul 2008 05:51:22 -0600 From: Matthew Wilcox <matthew@....cx> To: Andi Kleen <andi@...stfloor.org>, Greg KH <greg@...ah.com>, linux-kernel@...r.kernel.org Subject: Oops in sched_mc_power_savings_store I have no idea how you guys intended this to work, but here's the debugging work I've done so far. [ 89.210171] Call Trace: [ 89.210182] [<c011c0b3>] ? sched_mc_power_savings_store+0x0/0x4a [ 89.210198] [<c02908c0>] ? sysdev_class_store+0x38/0x40 [ 89.210213] [<c01a0b51>] ? sysfs_write_file+0xb9/0xe4 sched_mc_power_savings_store isn't a class attribute, it's a plain attribute. So the prototypes are different. This is why we try to load from address 2 -- it's actually the length parameter. I don't know how our typing system let this one through. I don't know if you want to fix this by adding an extra argument to the class_attribute show and store methods. I don't know if sched_mc_power_savings_store was intended to be a class attribute or not. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step." -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
