    Subject[PATCH 3.19.y-ckt 81/99] xfs: skip stale inodes in xfs_iflush_cluster
    Date
    3.19.8-ckt23 -stable review patch.  If anyone has any objections, please let me know.

    ---8<------------------------------------------------------------

    From: Dave Chinner <dchinner@redhat.com>

    commit 7d3aa7fe970791f1a674b14572a411accf2f4d4e upstream.

    We don't write back stale inodes so we should skip them in
    xfs_iflush_cluster, too.
