Subject: [PATCH 0/3] xfs: change available ranges in quota check

Hi,

This patch series changes available ranges of softlimit and
hardlimit in quota check, as follows.

(1) Consider new reservation for quota check
    The disk block reservation checks if (current usage + new
    reservation) reach the quota limit although the inode reservation
    does not use the new reservation for quota check. It should
    consider it, as well. This is mandatory for (2).

(2) Change available ranges of softlimit and hardlimit in quota check
    Currently xfs quota allows us to use disk blocks and inodes
    up to lower than quota limits. They should be used up to
    not greater than the limits.

Thanks,

---
