Change patch format to remove Git version
* Patches 0001-0122 only have the patch format modified
Update to the head of the upstream staging branch plus redhat patches
* Patches 0123-0134 & 1036-0142 are from the upstream staging branch
* Patches 0143-1046 have been submitted upstream
* Patch 0156 is a Red Hat only patch. Red Hat udev rules set ID_SERIAL
from 60-persistent-storage.rules instead of 55-scsi-sg3_id.rules.
Multipath's parse_vpd_pg83() function needs to match the ID_SERIAL
value from udev.
Rename files
* Previous patches 0123-0132 are now patches 1035 & 0147-0155

Subject: [PATCH] libmultipath: coalesce_paths(): stop triggering spurious
|
|
uevents
|
|
|
|
Since 0d66e03 ("libmultipath: force map reload if udev incomplete"), we
|
|
force-reload maps that we find incompletely initialized by udev. If
|
|
select_action returns ACT_NOTHING nonetheless, the map must be initialized
|
|
in udev, and thus and "add" uevent must have been seen already. Triggering
|
|
this event once more is unlikely to fix anything for real.
|
|
|
|
