Sorry if I suck, but right now I only have pre-made kernel releases from kernel.org. This bug in 5.4 messed up some of my dm-thin volumes which now took 28% of a dm-thin 14TB pool when the actual data is only using 4GB :( (at the same time it also shows my FS is full when of course it's not). I'll likely have to destroy the dm-thin to recover that space (or maybe not, we'll see), but I'm travelling and don't really have countless time to allocate to this. If 5.5.4 is supposed to fix this too, I'll build it, install it and hope it reclaims my lost dm-thin space, and if not suck up the deletion, re-creation and backup/restore.
