Thanks :-) Can you place a pointer to the tb array on the trans object? Another possibility is to have ->update return a kmalloced blob that contains ready-to-use binary data, so depending on the 'bool commit' the update hook would expect either tb[] (for validation) or a backend-maintained struct with the to-update values. In the quota case it would be a struct containing the u64 values. > I am also writing some userspace shell tests. Thats good, thanks Fernando!
