maillist inclusion category: bugfix bugzilla: 188812,https://gitee.com/openeuler/kernel/issues/I7E0YR CVE: NA
Reference: https://www.spinics.net/lists/kernel/msg4844759.html
----------------------------------------
Now we have a helper function dquot_dirty() to determine if dquot has DQ_MOD_B bit. dquot_active() can easily be misunderstood as a helper function to determine if dquot has DQ_ACTIVE_B bit. So we avoid this by renaming it to inode_quota_active() and later on we will add the helper function dquot_active() to determine if dquot has DQ_ACTIVE_B bit.
