Subject: [PATCH] libmultipath: fix mpp->hwe handling in sync_paths()
|
|
|
|
This is anologous to
|
|
|
|
1f96269 ("multipathd: fix mpp->hwe handling on path removal")
|
|
f6839eb ("multipathd: fix mpp->hwe handling when paths are freed")
|
|
|
|
When paths are removed from a map, we need to make sure that
|
|
mpp->hwe doesn't become stale.
