SubjectRegression: hibernation is broken since e6bc9de714972cac34daa1dc1567ee48a47a9342

at some point between 5.2 and 5.3 my laptop started to refuse
hibernating and come back to a full functional state. It's fully 100%
reproducible, no oopses or any other damage to the state seems to happen.

It took me a while to follow the trail down to this commit. If I revert
it from v5.6-rc1, the hibernation is back as in the old times.

Merge tag 'vfs-5.4-merge-1' of git://

Pull swap access updates from Darrick Wong:
"Prohibit writing to active swap files and swap partitions.

There's no non-malicious use case for allowing userspace to scribble
on storage that the kernel thinks it owns"

* tag 'vfs-5.4-merge-1' of git://
vfs: don't allow writes to swap files
mm: set S_SWAPFILE on blockdev swap devices

Is it possible to do anything?
