I think I found why that status code is defined in the UFSHCI 2.1
standard. From the UFS 2.0 standard: "TASK ABORTED - This status shall
be returned when a command is aborted by a command or task management
function on another I_T nexus and the Control mode page TAS bit is set
to one. Since in UFS there is only one I_T nexus and TAS bit is zero
TASK ABORTED status codes will never occur."

Bart.
