Re: weird swap device name

i have seen this on 13.* once. or similar thing. i attributed it to some kind of corruption

there, i had swap device with size i didn't add, but size was as if size of some other partition on some other device

this 3rd nonfunctional device was seemingly never used nor did i experience any visible data corruption anywhere. using zfs

problem seemed to appear after some sata devices went off bus and quickly reappeared

i don't know how to test this. seems like this needs fuzzing but don't know if vm would be enough

back then, everybody said that kernel doesn't allow it. yet it somehow did

i think i even have some swapinfo outputs saved. which i was told to be impossible. "never seen anything like this"

maybe this time this could be fixed?
