From ff6d6af2351caea7db681f4539d0d893e400557a Mon Sep 17 00:00:00 2001 From: Bill O'Donnell Date: Mon, 12 Oct 2015 18:21:22 +1100 Subject: 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 --- fs/xfs/xfs_dquot.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'fs/xfs/xfs_dquot.c') diff --git a/fs/xfs/xfs_dquot.c b/fs/xfs/xfs_dquot.c index 30cb3afb67f0..7ac6c5c586cb 100644 --- a/fs/xfs/xfs_dquot.c +++ b/fs/xfs/xfs_dquot.c @@ -75,9 +75,9 @@ xfs_qm_dqdestroy( ASSERT(list_empty(&dqp->q_lru)); mutex_destroy(&dqp->q_qlock); - kmem_zone_free(xfs_qm_dqzone, dqp); - XFS_STATS_DEC(xs_qm_dquot); + XFS_STATS_DEC(dqp->q_mount, xs_qm_dquot); + kmem_zone_free(xfs_qm_dqzone, dqp); } /* @@ -605,7 +605,7 @@ xfs_qm_dqread( break; } - XFS_STATS_INC(xs_qm_dquot); + XFS_STATS_INC(mp, xs_qm_dquot); trace_xfs_dqread(dqp); @@ -747,12 +747,12 @@ restart: mutex_unlock(&qi->qi_tree_lock); trace_xfs_dqget_hit(dqp); - XFS_STATS_INC(xs_qm_dqcachehits); + XFS_STATS_INC(mp, xs_qm_dqcachehits); *O_dqpp = dqp; return 0; } mutex_unlock(&qi->qi_tree_lock); - XFS_STATS_INC(xs_qm_dqcachemisses); + XFS_STATS_INC(mp, xs_qm_dqcachemisses); /* * Dquot cache miss.
