Otherwise it's pessimistic and may show low space although there's still some left. The df nubmers are lightly wrong in case of mixed block groups, but this is not a major usecase and can be addressed later. The RAID56 numbers are wrong almost the same way as before and will be addressed separately. === I'm most interested in the deadlock fix which finally made it in. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9e0af23764344f7f1b68e4eefbe7dc865018b63d https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux....
