Patch one is a preparation patch from Sagi and caches the nvme_ctrl in the nvme_request. This is not only useful for the tracepoints but for further development as well.
The second patch adds the controller IDs and if applicable the disk name to the tracepoints so we can distinguish between the individual controllers and disks. The patches are relative to the nvme-4.19 branch. Changes to v4: * Move nvme_ctrl caching into init_request callouts * I decided against renaming the qid tag in the tracepints but opt-in for a hwqid once we have all the infor available Johannes Thumshirn (1): nvme: trace: add disk name to tracepoints 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.h | 39 +++++++++++++++++++++++++-------------- drivers/nvme/target/loop.c | 1 + 7 files changed, 34 insertions(+), 16 deletions(-) -- 2.16.4
