From 917d0a4b95ea7ba01ed6296fb808f752d5d81107 Mon Sep 17 00:00:00 2001 From: TJ Adams Date: Mon, 6 Jul 2026 14:00:53 -0700 Subject: [PATCH] ata: libata-core: Skip HPA resize for locked drives Skip HPA resize in ata_hpa_resize() if the drive is security locked. If the drive is locked, the command to read the native max address fails with -EACCES, which currently causes the sticky quirk ATA_QUIRK_BROKEN_HPA to be set on the device. Setting this sticky quirk causes subsequent revalidations (after the drive is unlocked) to bypass HPA checks, preventing the unlocked drive from exposing its full native capacity without a reboot or device removal.
