[PATCH 37/43] libxfs: use opstate flags and functions for libxfs mount options

["Darrick J. Wong" <djwong@kernel.org>]

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

Port the two LIBXFS_MOUNT flags that actually do anything to set opstate
flags, in preparation for removing m_flags.

Signed-off-by: Darrick J. Wong <djwong@kernel.org>
