Subject: [PATCH] ublk: add missing DEL_DEV_ASYNC to unprivileged permission check
Date: Tue, 1 Sep 2026 22:24:38 +0800 [thread overview]
Message-ID: <20260901142438.237586-1-yi1tang.yang@gmail.com> (raw)
ublk_ctrl_uring_cmd_permission() is missing the UBLK_CMD_DEL_DEV_ASYNC
case, causing the command to always return -EINVAL for unprivileged
ublk devices. Fix it by adding the missing case.
Fixes: 13fe8e6825e4 ("ublk: add UBLK_CMD_DEL_DEV_ASYNC")
