Subject: [PATCH] quota: avoid increasing DQST_LOOKUPS when iterating over dirty/inuse list
Date: Thu, 26 Sep 2019 16:34:08 +0800 [thread overview]
Message-ID: <20190926083408.4269-1-cgxu519@zoho.com.cn> (raw)
It is meaningless to increase DQST_LOOKUPS number while iterating
over dirty/inuse list, so just avoid it.
