Subject: ocfs2: abstract the inline data dinode guard and cluster check
Date: Mon, 09 Nov 2026 20:21:00 +0800

Introduce ocfs2_dinode_has_inline_data() for the OCFS2_INLINE_DATA_FL
test that selects the id2.i_data union arm, and
ocfs2_dinode_has_inline_clusters() for the rule that an inline-data
inode must not also have allocated clusters.

The guard stays above the sub-checks: reading id_count or i_clusters
against the wrong id2 arm would produce false positives on valid inodes.

No functional change intended.
