This brings me back to the earlier question:
When my other FS died, scrub ran ok just earlier.
Now, having 2 btrfs sends (not incremental, full) fail with 2 kernels
would indicate that something might be wrong on the source filesystem.
Yet, last night's scrub ran fine too:

So, does scrub actually make sure everything on my filesystem is sane,
or can it miss some kinds of corruptions?
I can't run btrfsck on the filesystem because it's mounted and I have no
backup FS to boot from now until I fix my SSD.
