2022-08-09[user/ls]: List specific device fileJohn Jolly1-0/+1
When using the ls userspace program to list a specific device file, nothing would be displayed. This was because ls only tests for T_FILE and T_DIR. T_DEVICE files would fall through the case block. Adding T_DEVICE to the T_FILE case allows a device file to be listed. $ ls console console 3 19 0
