Subject: [PATCH 1/1] blk-mq: remove unused 'nr_expired' from blk_mq_hw_ctx
Date: Tue, 19 Mar 2019 23:05:18 +0800 [thread overview]
Message-ID: <1553007918-5026-1-git-send-email-dongli.zhang@oracle.com> (raw)
There is no usage of 'nr_expired'.
The 'nr_expired' was introduced by commit 1d9bd5161ba3 ("blk-mq: replace
timeout synchronization with a RCU and generation based scheme"). Its usage
was removed since commit 12f5b9314545 ("blk-mq: Remove generation
seqeunce").
