Btrfs: fix missing deleted items in btrfs_clean_quota_tree
Steps to reproduce:
i=0
ncases=100
mkfs.btrfs <disk>
mount <disk> <mnt>
btrfs quota enable <mnt>
btrfs qgroup create 2/1 <mnt>
while [ $i -le $ncases ]
do
btrfs qgroup create 1/$i <mnt>
btrfs qgroup assign 1/$i 2/1 <mnt>
i=$(($i+1))
done
btrfs quota disable <mnt>
umount <mnt>
btrfsck <mnt>
You can also use the commands:
btrfs-debug-tree <disk> | grep QGROUP
You will find there are still items existed.The reasons why this happens
is because the original code just checks slots[0]==0 and returns.
We try to fix it by deleting the leaf one by one.
