Currently we rely on fsfreeze/thaw commands disabling/enabling logging then having other commands check whether logging is disabled to avoid executing if they aren't safe for running while a filesystem is frozen. Instead, have an explicit whitelist of fsfreeze-safe commands, and consolidate logging and command enablement/disablement into a pair of helper functions: ga_set_frozen()/ga_unset_frozen() Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
