From 6c32fc0df9cd901add75618c831fb26a9eb742cb Mon Sep 17 00:00:00 2001 From: Alberto Faria Date: Sat, 29 Oct 2022 00:38:54 +0100 Subject: block/blkio: Make driver nvme-io_uring take a "path" instead of a "filename" The nvme-io_uring driver expects a character special file such as /dev/ng0n1. Follow the convention of having a "filename" option when a regular file is expected, and a "path" option otherwise. This makes io_uring the only libblkio-based driver with a "filename" option, as it accepts a regular file (even though it can also take a block special file).
