xfs: per-filesystem stats counter implementation
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. ] Signed-off-by: Bill O'Donnell <billodo@redhat.com> Reviewed-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
