    xfs: introduce xfs_bulkstat_ag_ichunk

    From: Jie Liu <jeff.liu at oracle.com>

    Introduce xfs_bulkstat_ag_ichunk() to process inodes in chunk with a
    pointer to a formatter function that will iget the inode and fill in
    the appropriate structure.

    Refactor xfs_bulkstat() with it.

    xfs: introduce xfs_bulkstat_grab_ichunk

    From: Jie Liu <jeff.liu at oracle.com>

    Introduce xfs_bulkstat_grab_ichunk() to look up an inode chunk in where
    the given inode resides, then grab the record.  Update the data for the
    pointed-to record if the inode was not the last in the chunk and there
    are some left allocated, return the grabbed inode count on success.

    Refactor xfs_bulkstat() with it.

    xfs: fix error handling at xfs_bulkstat

    From: Jie Liu <jeff.liu at oracle.com>

    We should not ignore the btree operation errors at xfs_bulkstat() but
    to propagate them if any. This patch fix two places in this function
    and the remaining things will be fixed with code refactoring thereafter.

    xfs: fix error handling at xfs_inumbers

    From: Jie Liu <jeff.liu at oracle.com>

    To fetch the file system number tables, we currently just ignore the
    errors and proceed to loop over the next AG or bump agino to the next
    chunk in case of btree operations failed, that is not properly because
    those errors might hint us potential file system problems.

    This patch rework xfs_inumbers() to handle the btree operation errors
    as well as the loop conditions.

    xfs: remove xfs_bulkstat_single

    From: Christoph Hellwig <hch at lst.de>

    xfs_bukstat_one doesn't have any failure case that would go away when
    called through xfs_bulkstat, so remove the fallback and the now unessecary
    xfs_bulkstat_single function.
