Subject: [PATCH 02/10] kexec: define kexec_in_progress in !CONFIG_KEXEC case
Date: Sat, 27 Jun 2015 22:47:24 -0700	[thread overview]
Message-ID: <1435470452-13471-2-git-send-email-kys@microsoft.com> (raw)
In-Reply-To: <1435470452-13471-1-git-send-email-kys@microsoft.com>

From: Vitaly Kuznetsov <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.
