22 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: do not start relocation until in progress drops are done We hit a bug with a recovering relocation on mount for one of our file systems in production. I reproduced this locally by injecting errors into snapshot delete with balance running at the same time.
