From: Bill O'Donnell Date: Mon, 12 Oct 2015 07:21:22 +0000 (+1100) Subject: xfs: per-filesystem stats counter implementation X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ff6d6af2351caea7db681f4539d0d893e400557a;p=linux-beck.git 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 Reviewed-by: Eric Sandeen Signed-off-by: Dave Chinner --- diff --git a/fs/xfs/libxfs/xfs_alloc.c b/fs/xfs/libxfs/xfs_alloc.c index ffad7f20342f..9b5da7e3b5c2 100644 --- a/fs/xfs/libxfs/xfs_alloc.c +++ b/fs/xfs/libxfs/xfs_alloc.c @@ -651,8 +651,8 @@ xfs_alloc_ag_vextent( -((long)(args->len)));
