[RFC PATCH v4 11/20] mm: split off __bdi_set_min_ratio() function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This splits off the __bdi_set_min_ratio() function from the
bdi_set_min_ratio() function. The __bdi_set_min_ratio() function will
also be called from the bdi_set_min_bytes() function, which will be
introduced in the next patch.
