I don't think the second condition you gave is relevant, because once the task_struct->fs pointer is nullified, this thread is not accounted in fs->users anymore. Since this thread doesn't count for neither fs->count nor n_fs, it is okay.

The first condition is indeed a problem. I'm not sure of the wanted fix (probably some kind of locking in copy_process, that while_each_thread could use too), but currently this race is bad.
