      ocfs2: Free up some space in the lvb · 4d3b83f7
      Mark Fasheh 提交于
      lvb_version doesn't need to be a whole 32 bits. Make it an 8 bit field to
      free up some space. This should be backwards compatible until we use one of
      the fields, in which case we'd bump the lvb version anyway.

      ocfs2: Remove special casing for inode creation in ocfs2_dentry_attach_lock() · 0027dd5b
      Mark Fasheh 提交于
      We can't use LKM_LOCAL for new dentry locks because an unlink and subsequent
      re-create of a name/inode pair may result in the lock still being mastered
      somewhere in the cluster.

      ocfs2: manually d_move() during ocfs2_rename() · 1ba9da2f
      Mark Fasheh 提交于
      Make use of FS_RENAME_DOES_D_MOVE to avoid a race condition that can occur
      during ->rename() if we d_move() outside of the parent directory cluster
      locks, and another node discovers the new name (created during the rename)
      and unlinks it. d_move() will unconditionally rehash a dentry - which will
      leave stale data in the system.

      [PATCH] Allow file systems to manually d_move() inside of ->rename() · 349457cc
      Mark Fasheh 提交于
      Some file systems want to manually d_move() the dentries involved in a
      rename.  We can do this by making use of the FS_ODD_RENAME flag if we just
      have nfs_rename() unconditionally do the d_move().  While there, we rename
      the flag to be more descriptive.
      
      OCFS2 uses this to protect that part of the rename operation with a cluster
      lock.

      ocfs2: Add dentry tracking API · 80c05846
      Mark Fasheh 提交于
      Replace the dentry vote mechanism with a cluster lock which covers a set
      of dentries. This allows us to force d_delete() only on nodes which actually
      care about an unlink.
      
      Every node that does a ->lookup() gets a read only lock on the dentry, until
      an unlink during which the unlinking node, will request an exclusive lock,
      forcing the other nodes who care about that dentry to d_delete() it. The
      effect is that we retain a very lightweight ->d_revalidate(), and at the
      same time get to make large improvements to the average case performance of
      the ocfs2 unlink and rename operations.
      
      This patch adds the higher level API and the dentry manipulation code.

      This patch adds the cluster lock type which OCFS2 can attach to
      dentries.  A small number of fs/ocfs2/dcache.c functions are stubbed
      out so that this change can compile.

      The OCFS2 DLM uses strlen() to determine lock name length, which excludes
