Subject: [PATCH] blk-iocost: drop selecting undefined BLK_RQ_IO_DATA_LEN
Date: Fri, 12 Nov 2021 10:37:28 +0100 [thread overview]
Message-ID: <20211112093728.3237-1-lukas.bulwahn@gmail.com> (raw)
Commit cd006509b0a9 ("blk-iocost: account for IO size when testing
latencies") selects the non-existing config BLK_RQ_IO_DATA_LEN in
config BLK_CGROUP_IOCOST.
Hence, ./scripts/checkkconfigsymbols.py warns:
BLK_RQ_IO_DATA_LEN
Referencing files: block/Kconfig
Probably, this select is just some unintended left-over from an earlier
draft version; BLK_RQ_IO_DATA_LEN was never defined in any commit in the
repository. So, drop this dead select to an undefined config.
Fixes: cd006509b0a9 ("blk-iocost: account for IO size when testing latencies")
