Hi! I test on my host and find below issue, i want to know how can fix it?
root@ubuntu ~/xfstests# ./check generic/015
FSTYP -- btrfs
PLATFORM -- Linux/x86_64 ubuntu 4.12.0-rc6
MKFS_OPTIONS -- /dev/sda2
MOUNT_OPTIONS -- /dev/sda2 /fs/scratch
generic/015 - output mismatch (see ~/xfstests/results//generic/015.out.bad)

I print _free to log and find after rm, the space do not free:
root@ubuntu ~/xfstests# cat log
/dev/sda2 btrfs 51200 16416 46052 27% /fs/scratch
46052
/dev/sda2 btrfs 51200 46144 17348 73% /fs/scratch
17348
/dev/sda2 btrfs 51200 46144 17348 73% /fs/scratch
17348
It makes me confused, and i am sure the file has removed and can not create size over 17348 file.
Is it a bug or something wrong with my host?
Thanks
Dai Xiang
