Fixed up the nvme driver to ensure passthrough commands go through the multipath start/end functions. Have the helper function take a request_queue parameter since the queue accumulating the stats for multipath isn't the same as the request's queue.=20 Keith Busch (2): block: export passthrough stats enabled nvme: add support multipath passthrough iostats block/blk-mq.c | 32 +------------------------------- drivers/nvme/host/ioctl.c | 4 ++++ drivers/nvme/host/multipath.c | 5 ++++- include/linux/blk-mq.h | 30 ++++++++++++++++++++++++++++++ 4 files changed, 39 insertions(+), 32 deletions(-) --=20 2.53.0-Meta
