Subject: [PATCH] udev: create symlinks and watch even in suspended state
|
|
|
|
If a dm device is suspended, we can't run blkid on it. But earlier
|
|
rules (e.g. 11-dm-parts.rules) might have imported previously scanned
|
|
properties from the udev db, in particular if the device had been correctly
|
|
set up beforehand (DM_UDEV_PRIMARY_SOURCE_FLAG==1). Symlinks for existing
|
|
ID_FS_xyz properties must be preserved in this case. Otherwise lower-priority
|
|
devices (such as multipath components) might take over the symlink
|
|
temporarily.
|
|
|
|
Likewise, we should't stop watching a temporarily suspended, but previously
|
|
correctly configured dm device.
