Subject: [patch V2 12/17] async: Adjust system_state checks
Date: Tue, 16 May 2017 20:42:43 +0200	[thread overview]
Message-ID: <20170516184735.865155020@linutronix.de> (raw)
In-Reply-To: 20170516184231.564888231@linutronix.de

[-- Attachment #1: async--Adjust-system_state-checks.patch --]
[-- Type: text/plain, Size: 1783 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.
