Subject: Re: [RFC v2 4/6] fs: distinguish between user initiated freeze and kernel initiated freeze
Date: Tue, 20 Apr 2021 13:46:26 +0100 [thread overview]
Message-ID: <20210420124626.GB3604224@infradead.org> (raw)
In-Reply-To: <20210417001026.23858-5-mcgrof@kernel.org>
Wouldn't it be simpler to just add a new flag to signal a kernel
initiated freeze, or even better the exact reason (suspend) instead of
overloading the state machine?
