Subject: [PATCH] ioengines: fix crash with --enghelp option
|
|
|
|
Since f6931a1dd35896433c8cc2e10de51372a2c496c4 commands like the
|
|
following segfault:
|
|
|
|
fio --enghelp=sg
|
|
fio --enghelp=sg,sg_write_mode
|
|
|
|
This is because free_ioengine() assumes that td->io_ops is not NULL.
|
|
Make this true when free_ioengine() is called by
|
|
fio_show_ioengine_help() to avoid the crash.
