"obj" is just as vapid and clueless as "ctx" is, and it seems very gratuitous to change this.

I'm sure you really don't want to edit GUID printk-like functions ever again, right?> static void vmbus_device_release(struct device *device) > { > - struct hyperv_device *device_ctx = device_to_hyperv_device(device); > + struct hyperv_device *device_obj = device_to_hyperv_device(device); > > - kfree(device_ctx); > + kfree(device_obj); > > - /* !!DO NOT REFERENCE device_ctx anymore at this point!! */ > + /* !!DO NOT REFERENCE device_obj anymore at this point!! */ > }I think by virtue of the kfree() right above this comment, it should be deleted. Especially as it is at the end of the function, making it pretty much impossible to make any sense here... Come on, global search-and-replace needs to be done in a sane manner, other wise you can just send me a vi macro to run on the code, it would be the same thing in the end (hint, don't do that, only one person has ever gotten away with doing that in the history of the kernel, in an act never to be ever repeated again.) thanks, greg k-h
