From ce32496ec1abe866225f2e2005ceda68cf4c7bf4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 6 Jan 2025 09:35:11 +0100 Subject: block: simplify tag allocation policy selection Use a plain BLK_MQ_F_* flag to select the round robin tag selection instead of overlaying an enum with just two possible values into the flags space. Doing so allows adding a BLK_MQ_F_MAX sentinel for simplified overflow checking in the messy debugfs helpers.
