Subject: [PATCH 04/11] fs: free inodes we no longer need
Date: Mon, 15 Jun 2020 08:02:22 +0200	[thread overview]
Message-ID: <20200615060229.7533-5-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200615060229.7533-1-s.hauer@pengutronix.de>

So far we freed the no longer needed inodes only at unmount time.
Let's trust our reference counting a bit more and free them once
the reference counter hits zero.
