After updating to latest upstream, bug2163711 can be fixed. We don't use rhel only udev rule anymore and we use the udev rules from upstream. So we don't need to modify our rhel only udev rule again. Resolves: bz#2163711 Signed-off-by: Xiao Ni <xni@redhat.com>

Subject: [PATCH 35/83] monitor: Avoid segfault when calling NULL
|
|
get_bad_blocks
|
|
|
|
Not all struct superswitch implement a get_bad_blocks() function,
|
|
yet mdmon seems to call it without checking for NULL and thus
|
|
occasionally segfaults in the test 10ddf-geometry.
|
|
|
|
Fix this by checking for NULL before calling it.
