Subject: [RFC PATCH 19/20] kexec: export kexec_in_progress for modules
Date: Wed, 27 May 2026 17:42:01 -0700 [thread overview]
Message-ID: <20260528004204.1484584-20-jloeser@linux.microsoft.com> (raw)
In-Reply-To: <20260528004204.1484584-1-jloeser@linux.microsoft.com>
Modules that register reboot notifiers may need to distinguish a
kexec from a regular reboot. Export kexec_in_progress so they can
check without requiring a built-in wrapper.
