Needs a better name. ZONE_DIRTY_CONGESTED ?
That might be confusing. The underlying BDI is not necessarily
congested. I accept your point though and will try thinking of a better
name.
ZONE_LOTS_DIRTY ?
I had changed it to
ZONE_TAIL_LRU_DIRTY, /* reclaim scanning has recently found
* many dirty file pages at the tail
* of the LRU.
*/
Is that reasonable?
Works for me.
