Subject: [PATCH 38/45] libxfs: use opstate flags and functions for libxfs mount options
Date: Wed, 19 Jan 2022 16:20:52 -0800	[thread overview]
Message-ID: <164263805261.860211.1342663364051871462.stgit@magnolia> (raw)
In-Reply-To: <164263784199.860211.7509808171577819673.stgit@magnolia>

From: Darrick J. Wong <djwong@kernel.org>

Port the three LIBXFS_MOUNT flags that actually do anything to set
opstate flags in preparation for removing m_flags in a later patch.
Retain the LIBXFS_MOUNT #defines so that libxfs clients can pass them
into libxfs_mount.
