From 738981bd74e89d5de012c56a20427e34c6937334 Mon Sep 17 00:00:00 2001 From: David Disseldorp Date: Wed, 19 Feb 2020 14:01:35 +0100 Subject: scsi: target: fix unmap_zeroes_data boolean initialisation The LIO unmap_zeroes_data device attribute is mapped to the LBPRZ flag in the READ CAPACITY(16) and Thin Provisioning VPD INQUIRY responses. The unmap_zeroes_data attribute is exposed via configfs, where any write value is correctly validated via strtobool(). However, when initialised via target_configure_unmap_from_queue() it takes the value of the device's max_write_zeroes_sectors queue limit, which is non-boolean. A non-boolean value can be read from configfs, but attempting to write the same value back results in -EINVAL, causing problems for configuration utilities such as targetcli.
