      [patch 3/3] OCFS2 Configurable timeouts - Protocol changes · 828ae6af
      Andrew Beekhof authored
      
      
      Modify the OCFS2 handshake to ensure essential timeouts are configured
      identically on all nodes.
      
      Only allow changes when there are no connected peers
      
      Improves the logic in o2net_advance_rx() which broke now that
      sizeof(struct o2net_handshake) is greater than sizeof(struct o2net_msg)
      
      Included is the field for userspace-heartbeat timeout to avoid the need for
      further protocol changes.
      
      Uses a global spinlock to ensure the decisions to update configfs entries
      are made on the correct value.  The region covered by the spinlock when
      incrementing the counter is much larger as this is the more critical case.

      ocfs2: Remove i_generation from inode lock names · 24c19ef4
      Mark Fasheh authored
      
      
      OCFS2 puts inode meta data in the "lock value block" provided by the DLM.
      Typically, i_generation is encoded in the lock name so that a deleted inode
      on and a new one in the same block don't share the same lvb.
      
      Unfortunately, that scheme means that the read in ocfs2_read_locked_inode()
      is potentially thrown away as soon as the meta data lock is taken - we
      cannot encode the lock name without first knowing i_generation, which
      requires a disk read.
      
      This patch encodes i_generation in the inode meta data lvb, and removes the
      value from the inode meta data lock name. This way, the read can be covered
      by a lock, and at the same time we can distinguish between an up to date and
      a stale LVB.
      
      This will help cold-cache stat(2) performance in particular.
      
      Since this patch changes the protocol version, we take the opportunity to do
      a minor re-organization of two of the LVB fields.

      ocfs2: Hook rest of the file system into dentry locking API · 379dfe9d
      Mark Fasheh authored
      
      
      Actually replace the vote calls with the new dentry operations. Make any
      necessary adjustments to get the scheme to work.
