It's also a kernel bug in btrfs, which given btrfs has only ever been a Technology Preview in RHEL, and was moved to being a deprecated feature in 7.4, I'd suggest that you shouldn't be looking for upstream support on btrfs. If you're tinkering with btrfs, don't be surprised at having to use a kernel from elsewhere, as suggested by Pete. RHEL advice would clearly be not to use btrfs. jh
