I get the following call trace about 0.6s after dnf completes an update which I imagine deletes many files. I'll try to reproduce and get /proc/lock_stat [ 95.674507] kernel: BUG: MAX_LOCKDEP_CHAIN_HLOCKS too low!
The message "BUG: MAX_LOCKDEP_CHAIN_HLOCKS too low" is related to lockdep and not a btrfs problem, but it appears from time to time and as Johannes said either increase the config variable, or ignore it.
