Subject: [PATCH v3 2/5] quota: rename dquot_active() to inode_quota_active()
Date: Fri, 30 Jun 2023 19:08:19 +0800 [thread overview]
Message-ID: <20230630110822.3881712-3-libaokun1@huawei.com> (raw)
In-Reply-To: <20230630110822.3881712-1-libaokun1@huawei.com>
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.

V2->V3:
Rename to inode_quota_active() instead of inode_dquot_active().
