Donnu if it's too late - was on vacation and this only arrived
Wednesday. Seems to be necessary to avoid introducing a regression
in virtio-mem.

Heh. Not too late for 5.14, but too late in the sense that I had
picked this one up manually already as commit 425bec0032f5
("virtio-mem: fix sleeping in RCU read side section in
virtio_mem_online_page_cb()").

Thanks Michael for sending this last minute and thanks Linus for picking 
it up independently early! Awesome :)
