ocfs2: Re-order iput in ocfs2_drop_dentry_lock
Do this to avoid a theoretical (I haven't seen this in practice) race where the downconvert thread might drop the dentry lock, allowing a remote unlink to proceed before dropping the inode locks. This could bounce access to the orphan dir between nodes. There doesn't seem to be a need to do the same in ocfs2_dentry_iput() as that's never called for the last ref drop from the downconvert thread. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
