... and on any arch, e.g. x86_64 (not just s390x as Jan previously reported [1])

Good catch, you're right. I'm also confused, before v7.2 swap worked on exfat,
now even with 82a81a7352bc ("exfat: add iomap buffered I/O support") [2]
and your fix 03a43677ca91 ("exfat: add swap_activate support") [3] is not
working. Obviously the fix was not good enough.

Kind regards,
Petr
