3d6ce9b308 Separate tests in slow and quick. The slow tests run xv6 out of 
memory, out of disk space, or test big directories.

Support -q option to run only the quick tests, which saves about
7mins.

Clean up driver by removing duplicated code.

2462656f21 [user/ls]: List specific device file 
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.
