From fb749a87f4536d2fa86ea135ae4eff1072903438 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 18 Apr 2022 06:53:06 +0200 Subject: null_blk: don't set the discard_alignment queue limit The discard_alignment queue limit is named a bit misleading means the offset into the block device at which the discard granularity starts. Setting it to the discard granularity as done by null_blk is mostly harmless but also useless.
