Subject: [PATCH 0/1] nilfs2: fix device cache flush in nilfs_sync_fs()

Hi Andrew,

Please add the following patch to the queue for the next merge window.

It ensures that nilfs_sync_fs() function sends a cache flush request
to the underlying device when required.  The current nilfs_sync_fs()
has a defect that it can skip the flush if only a small amount of data
is written.  The original cover letter can be seen at:

    "[PATCH v6 0/1] nilfs2: add missing blkdev_issue_flush() to
    nilfs_sync_fs()"

Thanks,
