If anyone has any objections, please let me know. ------------------ From: Yitang Yang [ Upstream commit e6ac1da6a53c5f670bf09e60a2500d15be68d2fc ] 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.
