Subject: [PATCH 11/17] apply obtain_device_list_from_udev to all libudev usage
|
|
|
|
udev_dev_is_md_component and udev_dev_is_mpath_component
|
|
are not used for obtaining the device list, but they still
|
|
use libudev for device info. When there are problems with
|
|
udev, these functions can get stuck. So, use the existing
|
|
obtain_device_list_from_udev config setting to also control
|
|
whether these "is component" functions are used, which gives
|
|
us a way to avoid using libudev entirely when it's causing
|
|
problems.
