backport d8c47cc7bf602ef73384a00869a70148146c1191 to linux-5.15.y

Hi,

Can you please help in back porting the below patch to linux-5.15.y stable tree: commit d8c47cc7bf602ef73384a00869a70148146c1191("mm: page_io: fix psi memory pressure error on cold swapins") .

With the absence of this patch we are seeing some user space tools, like Android low memory killer based on PSI events, bit aggressive as it makes the PSI is accounted for even cold swapin on a device where swap is mounted on a zram with slower backing dev.

Thanks, Charan
