Description

After system boot, schedpaging() kicks off a full scan of all memory pages until pageout_sample_cnt >= pageout_sample_lim, in order to calibrate the speed at which memory pages can be scanned. Once this is determined, the initial paging parameters are set and setupclock() is called again.

However, #13097 inadvertently changed this so that the parameters are not set until pageout is woken up for a real memory shortage.
