Hi,

In FreeBSD 11, there is something new in top(1) : laundry memory stats.
 
Ex:
Mem: 884M Active, 1330M Inact, 415M Laundry, 5175M Wired, 782M Buf, 84M
Free

Can someone explain what is this memory please ?

man top:
   Physical Memory Stats
       Active:
              number of bytes active

       Inact: number of clean bytes inactive

       Laundry:
              number of dirty bytes queued for laundering

Thanks. Regards,
