Subject: [PATCH 02/43] xfs: remove support for disabling quota accounting on a mounted file system
Date: Mon, 13 Sep 2021 19:40:10 -0700	[thread overview]
Message-ID: <163158721096.1604118.17353772572397459905.stgit@magnolia> (raw)
In-Reply-To: <163158719952.1604118.14415288328687941574.stgit@magnolia>

From: Christoph Hellwig <hch@lst.de>

Source kernel commit: 40b52225e58cd3adf9358146b4b39dccfbfe5892

Disabling quota accounting is hairy, racy code with all kinds of pitfalls.
And it has a very strange mind set, as quota accounting (unlike
enforcement) really is a propery of the on-disk format.  There is no good
use case for supporting this.
