Subject: [PATCH v3] block: delete unused config BLK_RQ_IO_DATA_LEN
Date: Tue, 21 Jul 2020 10:10:52 +0800 [thread overview]
Message-ID: <1595297452-38695-1-git-send-email-jiufei.xue@linux.alibaba.com> (raw)
Config BLK_RQ_IO_DATA_LEN was once used to enable the io_data_len field
in reqeust to remember blk_rq_bytes() at the time the request gets
issued. However io_data_len is replaced by blk_rq_stats_sectors() and
the config is not used now. So delete it.
