Subject: [PATCH] Revert "multipathd: uev_trigger(): handle incomplete ADD
|
|
events"
|
|
|
|
cb10d38 ("multipathd: uev_trigger(): handle incomplete ADD events") was an
|
|
attempt to fix issues with incompletely initialized multipath maps observed
|
|
in various scenarious. However, that patch was wrong. Spurious "change" events
|
|
as this patch would generate have no effect, because they are ignored by
|
|
the device-mapper udev rules. The correct fix for the problem we were
|
|
facing is 0d66e03 ("libmultipath: force map reload if udev incomplete"),
|
|
which forces a full map reload.
