From 869d9b41d4c8c7bb412c56e02a0e873141fe6c48 Mon Sep 17 00:00:00 2001 From: Sreekanth Reddy Date: Mon, 26 Jul 2021 17:24:02 +0530 Subject: [PATCH] scsi: core: Avoid printing an error if target_alloc() returns -ENXIO [ Upstream commit 70edd2e6f652f67d854981fd67f9ad0f1deaea92 ] Avoid printing a 'target allocation failed' error if the driver target_alloc() callback function returns -ENXIO. This return value indicates that the corresponding H:C:T:L entry is empty. Removing this error reduces the scan time if the user issues SCAN_WILD_CARD scan operation through sysfs parameter on a host with a lot of empty H:C:T:L entries. Avoiding the printk on -ENXIO matches the behavior of the other callback functions during scanning.
