[PATCH v2 6/9] mpathpersist: initialize data structures only once

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We now have the possibility to run several PR commands in a single
mpathpersist invocation. Run initialization / discovery and teardown
only once at program invocation / exit.
