Subject: [PATCH 25/43] xfs: convert mount flags to features
Date: Mon, 13 Sep 2021 19:42:16 -0700	[thread overview]
Message-ID: <163158733660.1604118.8914008454755284421.stgit@magnolia> (raw)
In-Reply-To: <163158719952.1604118.14415288328687941574.stgit@magnolia>

From: Dave Chinner <dchinner@redhat.com>

Source kernel commit: 0560f31a09e523090d1ab2bfe21c69d028c2bdf2

Replace m_flags feature checks with xfs_has_<feature>() calls and
rework the setup code to set flags in m_features.
