# 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.
