Regarding 2), it seems multiple instances of nilfs_cleanerd can be started for 
one filesystem (which leads to metadata corruption, as per my earlier 
``Regarding problem with nilfs_cleanerd - part 2 and Nilfs_cleanerd err=-17'' 
mail).

Is that intentional? Should we guard on nilfs_cleanerd level, or on kernel 
level?
