Subject: [PATCH] libmultipath: make dm_flush_maps only return 0 on success
|
|
|
785c99 |
|
|
|
785c99 |
dm_flush_maps() returned both 0 and 1 on error, depending on which part
|
|
|
785c99 |
of the function it was in, but the caller was always treating 0 as a
|
|
|
785c99 |
success. Make dm_flush_maps() always return 1 on error and 0 on success.
