Callbacks provided for module parameters are executed both after the module is loaded, when a user alters it via sysfs, e.g echo bar > /sys/modules/zfs/parameters/foo as well as when the module is loaded with an argument, e.g. modprobe zfs foo=bar In the latter case, the init functions likely have not run yet, including spa_init() which initializes the namespace lock so it is safe to use. Instead of immediately taking the namespace lock and attemping to iterate over initialized spa structures, check whether spa_mode_global is nonzero. This is set by spa_init() after it has initialized the namespace lock.
