Subject: [PATCH] rules: move cpu hotplug rule to separate file
|
|
|
a19bc6 |
|
|
|
a19bc6 |
In kdump initrd we don't want to automatically bring online all
|
|
|
a19bc6 |
available CPUs. Hence, kdump maintainers can easily mask the rule by
|
|
|
a19bc6 |
placing symlink to /dev/null with the same name in /etc/udev/rules.d

[msekleta: note that this is just part of the fix for #1266322, in
|
|
|
a19bc6 |
order to fix the bug it is necessary to actually mask the newly added
|
|
|
a19bc6 |
rule when generating kdump initrd]
