Konrad Sztyber 07be7ca0ad bdev/nvme: use non-ext IO functions if possible ... Patch 55f947933 ("bdev: remove spdk_bdev_ext_io_opts from spdk_bdev_io") changed the way bdev_nvme submits IO to the NVMe driver causing performance degradation for requests with iovcnt = 1, as they also had to go through the path that executes the reset_sgl/next_sge callbacks. This patch reverts those changes back to the original code checking iovcnt and using the non-SGL functions if possible.
