From 13202ebf5f331ca83f5ab47eb90ca4ef5489ac80 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Wed, 1 Dec 2021 14:28:30 +0000 Subject: scsi: sd_zbc: Simplify zone full condition check According to the ZBC (and ZAC) specification, a zone that has Zone Type set to Conventional, must also have its Zone Condition set to "Not Write Pointer". Therefore, a conventional zone will never have Zone Condition set to "Full", which means that we can omit the non-conventional prerequisite from the zone full condition check.
