commit 5e435c92464bba65df27315ea1e25ab06939ddad
Author: Matthew Dillon <dillon@apollo.backplane.com>
Date:   Tue Dec 2 18:11:43 2008 -0800

    HAMMER Filesystem changes:
    * Add version checking to the hammer mount code.
    * Add ioctls to fetch the hammer filesystem version and to upgrade it,
      to support future filesystem revisions.
    * Rewrite the algorithm used to integrate reservations with the blockmap
      allocate/free code to fix a bug.  hammer_buffers were sometimes not
      being properly destroyed causing conflicts with later reallocations.
    * Add support for up to four directory hash algorithms.  Add flexibility
      to the namekey iterator API to allow the algorithm to control the
      iteration space.
    * When iterating memory with the CURSOR_DELETE_VISIBILITY flag set, ignore
      the record deleted flags.
    HAMMER Utilities changes:
    * Add two new hammer directives, 'version' and 'version-upgrade'.
    * Change hammer namekey directive to 'namekey1' and 'namekey2', to support
      generating directory hashes for different hashing algorithms.
    * Change hammer cleanup to still prune for existing snapshots even if
      new snapshot generation is disabled.
    * Change hammer cleanup's default snapshots config for temporary
      filesystems from 'snapshots 0d 60d' to 'snapshots 0d 0d'.
