sys/kern : subr_hibernate.c
Log message:
increase hibernate writeout speed a little. modern machines have vast
tracts of unused memory, and the empty-space RLE scanner (uvm_page_rle)
would rescan for empty space needlessly wasting excessive cpu time
16G machine, 100sec -> 9sec
40G machine, 325sec -> 28sec
