Subject: [PATCH] multipathd: function return value tweaks
|
|
|
|
In cli_add_map() the return value of get_refwwid is never used, and
|
|
refwwid is checked to see if the function returned successfully, so the
|
|
return value doesn't need to be saved.
|
|
|
|
In resize_map, if setup_map fails, multipathd shouldn't attempt to
|
|
create the device with resulting params string. It should just fail
|
|
instead. Found by coverity.
