Subject: [PATCH] libmultipath: pathinfo: call filter_property only with
|
|
DI_BLACKLIST
|
|
|
|
With the previous change to call filter_property() after sysfs_pathinfo(),
|
|
it can't happen any more that filter_property() is called from pathinfo
|
|
with uid_attribute not set. This may cause pathinfo() to return failure
|
|
in some cases where it should actually proceed (e.g. when called from
|
|
"multipath -m" -> get_refwwid(). Therefore, don't call filter_property()
|
|
any more unless DI_BLACKLIST is set.
