From 37105615f73125cb0466c09796f277a4c46d9295 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 1 Jul 2024 07:17:51 +0200 Subject: [PATCH] block: don't reduce max_sectors based on io_opt Don't reduce the max_sectors value below the normal cap when the driver advertsizes a very low io_opt. This restores the behavior we had before the recent changes to the max_sectors calculation.
