Subject: [PATCH] libmpathpersist: allow using libmultipath
|
|
{get,put}_multipath_config
|
|
|
|
Provide an alternative init function libmpathpersist_init() which
|
|
avoids allocating a new struct config, simply using libmultipath's
|
|
internal implementation. This causes a minor version bump for
|
|
libmpathpersist.
