ocfs2: use retval instead of status for checking error

2015-06-25T00:49:39+00:00

The use of 'status' in __ocfs2_add_entry() can return wrong value. Some functions' return value in __ocfs2_add_entry(), i.e ocfs2_journal_access_di() is saved to 'status'. But 'status' is not used in 'bail' label for returning result of __ocfs2_add_entry(). So use retval instead of status.

ocfs2: reflink: fix slow unlink for refcounted file

2014-12-19T03:08:11+00:00

When running ocfs2 test suite multiple nodes reflink stress test, for a 4 nodes cluster, every unlink() for refcounted file needs about 700s. The slow unlink is caused by the contention of refcount tree lock since all nodes are unlink files using the same refcount tree. When the unlinking file have many extents(over 1600 in our test), most of the extents has refcounted flag set. In ocfs2_commit_truncate(), it will execute the following call trace for every extents. This means it needs get and released refcount tree lock about 1600 times. And when several nodes are do this at the same time, the performance will be very low. ocfs2_remove_btree_range() -- ocfs2_lock_refcount_tree() ---- ocfs2_refcount_lock() ------ __ocfs2_cluster_lock() ocfs2_refcount_lock() is costly, move it to ocfs2_commit_truncate() to do lock/unlock once can improve a lot performance.

ocfs2: do not set filesystem readonly if link down

2014-12-11T01:41:03+00:00

Do not set the filesystem readonly if the storage link is down. In this case, metadata is not corrupted and only -EIO is returned. And if it is indeed corrupted metadata, it has already called ocfs2_error() in ocfs2_validate_inode_block().
