Subject: [PATCH] libmultipath: fix disassemble status for
|
|
historical-service-time PS
|
|
|
|
The historical-service-time path selector prints out 2 path group status
|
|
arguments. This is the only path selector that uses the group status
|
|
arguments. All the others only have path status arguments.
|
|
disassemble_status() was expecting the number of group status arguments
|
|
to always be zero, causing it to fail at disassembling the status of
|
|
devices that use historical-service-time path selector. Now multipath
|
|
actually checks the number of group arguments, and skips them.
