Thanks that you can follow a renaming for this direction in principle.

This was not my intention for such an use case.

I am proposing some small software updates according to such a design pattern.

Do you reject also update steps like the following then?

* drm/ttm: Use kmalloc_array() in two (or four?) functions"

* drm/ttm: Less function calls in ttm_dma_pool_init() after error detection

* Would you like to improve the usage of the variables "n" and "t"
  in the function "ttm_dma_pool_init" any further as Joe Perches suggested it?

Do you find another software evolution interesting according to a recent commit?
