I have incorportated them all. CONFIG_OCFS2_FS_STATS is enabled and CONFIG_DEBUG_LOCK_ALLOC is disabled. Statistics now look like - ocfs2_write_ctxt: 2144 - 2136 = 8 ocfs2_inode_info: 1960 - 1848 = 112 ocfs2_journal: 168 - 160 = 8 ocfs2_lock_res: 336 - 304 = 32 ocfs2_refcount_tree: 512 - 472 = 40 Signed-off-by: Goldwyn Rodrigues Signed-off-by: Joel Becker --- fs/ocfs2/journal.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'fs/ocfs2/journal.h') diff --git a/fs/ocfs2/journal.h b/fs/ocfs2/journal.h index b5baaa8e710..43e56b97f9c 100644 --- a/fs/ocfs2/journal.h +++ b/fs/ocfs2/journal.h @@ -67,11 +67,12 @@ struct ocfs2_journal { struct buffer_head *j_bh; /* Journal disk inode block */ atomic_t j_num_trans; /* Number of transactions * currently in the system. */ + spinlock_t j_lock; unsigned long j_trans_id; struct rw_semaphore j_trans_barrier; wait_queue_head_t j_checkpointed; - spinlock_t j_lock; + /* both fields protected by j_lock*/ struct list_head j_la_cleanups; struct work_struct j_recovery_work; }; -- cgit v1.2.3-18-g5258
