Subject: [PATCH] kexec: Fix omitting offset in extended crashkernel syntax
Date: Tue, 14 Jul 2009 12:18:58 +0900 [thread overview]
Message-ID: <4A5BF922.2000503@jp.fujitsu.com> (raw)
Setting
"crashkernel=512M-2G:64M,2G-:128M"
does not work but it turns to work if it has a trailing-whitespace,
like
"crashkernel=512M-2G:64M,2G-:128M ".
It was because of a bug in the parser, running over the cmdline.
This patch adds a check of the termination.
