From: Bean Huo <beanhuo@micron.com> stable inclusion from stable-v5.10.137 commit 706960d328f5bdb1a9cde0b17a98ab84a59eed8e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 679c54f2de672b7d79d02f8c4ad483ff6dd8ce2e ] Use command_id instead of req->tag in trace_nvme_complete_rq(), because of commit e7006de6c238 ("nvme: code command_id with a genctr for use authentication after release"), cmd->common.command_id is set to ((genctl & 0xf)< 12 | req->tag), no longer req->tag, which makes cid in trace_nvme_complete_rq and trace_nvme_setup_cmd are not the same.
