++ * The kobject release method must not be placed in the module itself,
++ * otherwise we are subject to module unload races.
++ *
++ * The release method is called when the last reference to the kobject is
++ * dropped. It may be called by any other kernel code that drops the last
++ * reference.
++ *
++ * The release method suffers from module unload race. We may prevent the
++ * module from being unloaded at the start of the release method (using
++ * increased module reference count or synchronizing against the release
++ * method), however there is no way to prevent the module from being
++ * unloaded at the end of the release method.
++ *
++ * If this code were placed in the dm module, the following race may
++ * happen:
++ *  1. Some other process takes a reference to dm kobject
++ *  2. The user issues ioctl function to unload the dm device
++ *  3. dm_sysfs_exit calls kobject_put, however the object is not released
++ *     because of the other reference taken at step 1
++ *  4. dm_sysfs_exit waits on the completion
++ *  5. The other process that took the reference in step 1 drops it,
++ *     dm_kobject_release is called from this process
++ *  6. dm_kobject_release calls complete()
++ *  7. a reschedule happens before dm_kobject_release returns
++ *  8. dm_sysfs_exit continues, the dm device is unloaded, module reference
++ *     count is decremented
++ *  9. The user unloads the dm module
++ * 10. The other process that was rescheduled in step 7 continues to run,
++ *     it is now executing code in unloaded module, so it crashes
++ *
++ * Note that if the process that takes the foreign reference to dm kobject
++ * has a low priority and the system is sufficiently loaded with
++ * higher-priority processes that prevent the low-priority process from
++ * being scheduled long enough, this bug may really happen.
++ *
++ * In order to fix this module unload race, we place the release method
++ * into a helper code that is compiled directly into the kernel.
