From ac9f0c810684a1b161c18eb4b91ce84cbc13c91d Mon Sep 17 00:00:00 2001 From: Anton Lundin Date: Thu, 3 Feb 2022 10:41:35 +0100 Subject: ata: libata-core: Introduce ATA_HORKAGE_NO_LOG_DIR horkage 06f6c4c6c3e8 ("ata: libata: add missing ata_identify_page_supported() calls") introduced additional calls to ata_identify_page_supported(), thus also adding indirectly accesses to the device log directory log page through ata_log_supported(). Reading this log page causes SATADOM-ML 3ME devices to lock up. Introduce the horkage flag ATA_HORKAGE_NO_LOG_DIR to prevent accesses to the log directory in ata_log_supported() and add a blacklist entry with this flag for "SATADOM-ML 3ME" devices.
