- * The 1/4 region under the global dirty thresh is for smooth dirty throttling:
- *
- * (thresh - thresh/DIRTY_FULL_SCOPE, thresh)
- *
- * Further beyond, all dirtier tasks will enter a loop waiting (possibly long
- * time) for the dirty pages to drop, unless written enough pages.
- *
* The global dirty threshold is normally equal to the global dirty limit,
* except when the system suddenly allocates a lot of anonymous memory and
* knocks down the global dirty threshold quickly, in which case the global
* dirty limit will follow down slowly to prevent livelocking all dirtier tasks.
