The xfs checks quota when reserving disk blocks and inodes. In the block
reservation it checks if the total number of blocks including current
usage and new reservation reach quota. However, in the inode reservation
it checks using the total number of inodes including only current usage
without new reservation. It should include the new one, as well.
