From 46eca4702d93dbb8ac1c8fa84e5838fc8a1e82a0 Mon Sep 17 00:00:00 2001 From: Chaitanya Kulkarni Date: Sun, 13 Jun 2021 18:58:46 -0700 Subject: [PATCH] nvmet: use req->cmd directly in bdev-ns fast path The function nvmet_bdev_parse_io_cmd() is called from the fast path. The local variable to that function cmd is only used once. Remove the local variable and use req->cmd directly.
