From bf1b4659dc278b68f22b11b2c5fe7e3eb96e75a7 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Thu, 28 Jan 2021 14:56:58 +0900 Subject: [PATCH] scsi: sd: Warn if unsupported ZBC device is probed In sd_probe(), print a warning if CONFIG_BLK_DEV_ZONED is disabled and a TYPE_ZBC device is found. While at it, use IS_ENABLED() to test if CONFIG_BLK_DEV_ZONED is enabled instead using of a #ifdef.
