That's a known apparent false-positive warning on current 4.6-rc kernel btrfs. The destroy-inode bit is related to a file deletion happening in the normal order of things, where this warning code is run, and apparently triggers even under normal operations. It's related to some btrfs feature (I think either snapshotting or quotas, but don't recall which) I don't use here so I don't seem the warnings, but there's several threads where people have reported the warnings, so it's apparently quite commonly triggered, but nobody has reported any further problems even where the warnings are coming in the hundreds due to their use-case, so as I said, apparently a false-positive induced by normal operations. I'd expect the warning to be either fixed to only warn when there's an actual issue, or be silenced, by 4.6 release. If you want further details, as I said, there's at least two other threads with people reporting and discussing it, so read the last week or two of the list archive (or even just the non-patch original thread starter posts) and you'll find them. -- Duncan - List replies preferred.
