This patch series is based on/inspired by Johannes Thumshirn that improves the nvme trace events.
The first one from Sagi is saving the nvme_ctrl in the driver request data so we can reference it in other places, both for this series and future developments. The others are adding and simplifying the nvme traces so we can see information to uniquely identify what hardware the trace event is showing, and filter events for specific hardware. v2 -> v3: Removed unrelated code that leaked into the previous series Added helpers for setting the qid and disk name fields Simplified printing the disk name: it's already null terminated, so don't need to define the limit. Updated change logs Minor code formatting updates Added Reviewed-by for Sagi's patch v1 -> v2: Dropped the blk-mq patch as there were pre-existing ways to get to the desired information without introducing a new API Changelog typo fixups Keith Busch (3): nvme: use hw qid in trace events nvme: add controller name to trace events nvme: add disk name to trace events Sagi Grimberg (1): nvme: cache struct nvme_ctrl reference to struct nvme_request drivers/nvme/host/core.c | 5 +- drivers/nvme/host/fc.c | 1 + drivers/nvme/host/nvme.h | 1 + drivers/nvme/host/pci.c | 2 + drivers/nvme/host/rdma.c | 1 + drivers/nvme/host/trace.c | 11 ++++ drivers/nvme/host/trace.h | 137 +++++++++++++++++++++++++-------------------- drivers/nvme/target/loop.c | 1 + 8 files changed, 93 insertions(+), 66 deletions(-) -- 2.14.3
