I thought it had been picked up by akpm (see "[alternative-merged] > vfs-partially-revert-dont-allow-writes-to-swap-files.patch removed from > -mm tree" from 5 March), but it's not in mmotm now, oop. Things which are advertised as "hibernate: ..." tend not to survive my morning email triage :( > so I'll put this in my > vfs tree for 5.7. Thanks. But I assume that "it turns out that userspace hibernation requires the ability to write the hibernation image to a swap device" means we've regressed userspace hibernation. So I'd say either "5.6 with a cc:stable" or "5.7-rc1 with a cc:stable" if we're being more cautious.
