Subject: [PATCH 23/41] fs/adfs: dir: switch to iterate_shared method
Date: Mon, 09 Dec 2019 11:10:11 +0000	[thread overview]
Message-ID: <E1ieGvb-0004cC-L0@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20191209110731.GD25745@shell.armlinux.org.uk>

There is nothing in our readdir (aka iterate) method that relies on
the directory inode being exclusively locked, so switch to using the
iterate_shared() hook rather than iterate().
