Subject: [PATCH 03/10] quota: Introduce dquot_enable_sb()
Date: Wed, 30 Oct 2019 16:26:55 +0100 [thread overview]
Message-ID: <20191030152702.14269-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20191030152702.14269-1-s.hauer@pengutronix.de>
To support filesystems that do not store the quota informations in an
inode create dquot_enable_sb(). This is a variant of dquot_enable()
which takes a superblock instead of an inode This is a variant of
dquot_enable() which takes a superblock instead of an inode.
