This patch series based on/inspired by Johannes Thumshirn that improves the nvme trace events.
The 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 the more useful information to uniquely identify what hardware the trace event is showing, and filter events for specific hardware. 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: trace nvme queue identifiers nvme: trace controller name nvme: add disk name to tracepoints Sagi Grimberg (1): nvme: cache struct nvme_ctrl reference to struct nvme_request drivers/nvme/host/core.c | 7 +++--- 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 | 61 ++++++++++++++++++++++------------------------ drivers/nvme/target/loop.c | 1 + 8 files changed, 49 insertions(+), 36 deletions(-) -- 2.14.3
