From 888545cb43d7639457883dc325c303a3737c0a64 Mon Sep 17 00:00:00 2001 From: Anuj Gupta Date: Tue, 17 Jan 2023 17:36:37 +0530 Subject: [PATCH] nvme: set REQ_ALLOC_CACHE for uring-passthru request This patch sets REQ_ALLOC_CACHE flag for uring-passthru requests. This is a prep-patch so that normal / IRQ-driven uring-passthru I/Os can also leverage bio-cache.
