    xfs: per-filesystem stats counter implementation · ff6d6af2
    Bill O'Donnell authored
    This patch modifies the stats counting macros and the callers
    to those macros to properly increment, decrement, and add-to
    the xfs stats counts. The counts for global and per-fs stats
    are correctly advanced, and cleared by writing a "1" to the
    corresponding clear file.
    global counts: /sys/fs/xfs/stats/stats
    per-fs counts: /sys/fs/xfs/sda*/stats/stats
    global clear:  /sys/fs/xfs/stats/stats_clear
    per-fs clear:  /sys/fs/xfs/sda*/stats/stats_clear
    [dchinner: cleaned up macro variables, removed CONFIG_FS_PROC around
     stats structures and macros. ]
