Subject: [PATCH v2 10/19] ublk: support UBLK_F_INTEGRITY
Date: Fri, 2 Jan 2026 17:45:20 -0700 [thread overview]
Message-ID: <20260103004529.1582405-11-csander@purestorage.com> (raw)
In-Reply-To: <20260103004529.1582405-1-csander@purestorage.com>
From: Stanley Zhang <stazhang@purestorage.com>
Now that all the components of the ublk integrity feature have been
implemented, add UBLK_F_INTEGRITY to UBLK_F_ALL, conditional on block
layer integrity support (CONFIG_BLK_DEV_INTEGRITY). This allows ublk
servers to create ublk devices with UBLK_F_INTEGRITY set and
UBLK_U_CMD_GET_FEATURES to report the feature as supported.
