Subject: Re: [PATCH v4 1/2] kexec: Add helper to report an active kexec reboot
Date: Fri, 09 Oct 2026 10:28:56 +0000 [thread overview]
Message-ID: <sashiko-outbox-165237@kernel.org> (raw)
In-Reply-To: <20261009102236.3361019-1-shradhagupta@linux.microsoft.com>
> A shutdown callback in a loadable module may need to distinguish a
> kexec reboot from a normal restart, halt, or poweroff. The Hyper-V
> VMBus driver needs this distinction when moving its kexec cleanup into
> a common syscore shutdown callback.
>
> Add kexec_is_in_progress() and export it to GPL modules so the callback
> can remain guarded when VMBus is built as a module. Provide a false
> inline implementation when CONFIG_KEXEC_CORE is disabled.
>
> The helper reports only the normal kexec reboot path. Crash kexec and
> preserve-context kexec do not set this state.
