				# These tests exercise a few basic cases for the sendfile() syscall:
				# - successful operation.
				# - sendfile() starts an async disk read but that async I/O fails.
				# - sendfile() fails to read an indirect block and thus cannot
				# even start an async I/O.
				#
				# In all cases we request some read ahead in addition to
				# the data to be sent to the socket.
