Subject: [patch 12/18] async: Adjust system_state checks
Date: Sun, 14 May 2017 20:27:28 +0200	[thread overview]
Message-ID: <20170514183613.422834482@linutronix.de> (raw)
In-Reply-To: 20170514182716.347236777@linutronix.de

[-- Attachment #1: async--Adjust-system_state-checks.patch --]
[-- Type: text/plain, Size: 1777 bytes --]

To enable smp_processor_id() and might_sleep() debug checks earlier, it's
required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING.

Adjust the system_state check in async_run_entry_fn() and
async_synchronize_cookie_domain() to handle the extra states.
