Subject: [PATCH v3 2/5] kexec: define kexec_in_progress in !CONFIG_KEXEC case
Date: Thu, 25 Jun 2015 11:58:03 +0200 [thread overview]
Message-ID: <1435226286-24842-3-git-send-email-vkuznets@redhat.com> (raw)
In-Reply-To: <1435226286-24842-1-git-send-email-vkuznets@redhat.com>
If some piece of code wants to check kexec_in_progress it has to be put
in #ifdef CONFIG_KEXEC block to not break the build in !CONFIG_KEXEC
case. Overcome this limitation by defining kexec_in_progress to false.
