[PATCH] kexec-tools: Add --append option for s390

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Simon,

From: Michael Holzheu <holzheu@xxxxxxxxxxxxxxxxxx>

All architectures define the "--append" option together with the
"--command-line" option to specify kernel parameters. This option
is also used by kdump init scripts. In order to be compatible this
patch introduces the "--append" option also for s390. In addition
to that the help text is adjusted so that it is now the same as on
all other architectures.
