Shuhei Matsumoto 2a6a64485c bdev/nvme: Add bdev_nvme_get_io_paths RPC to monitor I/O path states ... Add an new RPC bdev_nvme_get_io_paths to query all active I/O paths. One io_path belongs to One nvme_bdev_channel. Each nvme_bdev_channel is associated with one nvme_bdev. If the RPC bdev_nvme_get_io_paths has a bdev name as a parameter it can use spdk_for_each_channel() simply for the corresponding nvme_bdev. However, users will want to know I/O paths of all nvme_bdevs like the RPC bdev_get_bdevs. One io_path has one nvme_qpair. One nvme_qpair belongs to one nvme_poll_group. By relying on these relationships, the RPC bdev_nvme_get_io_paths traverses all nvme_poll_groups by using spdk_for_each_channel() to g_bdev_nvme_ctrlrs. The RPC bdev_nvme_get_io_paths has two modes, display all or the specified NVMe bdev's active I/O paths. The specified bdev name is used just for comparison and empty array is returned if no matched io_path is found.
