Subject: [UPDATE] Directory index for ext2
Date:	 Thu, 31 May 2001 18:13:43 +0200
Cc:	 Alexander Viro <viro@math.psu.edu>,

Changes:

  - Freshen to 2.4.5
  - EXT2_FEATURE_COMPAT_DIR_INDEX flag finalized
  - Break up ext2_add_entry for aesthetic reasons (Al Viro)
  - Handle more than 64K directories per directory (Andreas Dilger)
  - Bug fix: new inode no longer inherits index flag (Andreas Dilger)
  - Bug fix: correct handling of error on index create (Al Viro)

To-Do:

  - More factoring of ext2_add_entry
  - Fall back to linear search in case of corrupted index
  - Finalize hash function

The patch is available at:

    http://nl.linux.org/~phillips/htree/dx.pcache-2.4.5   

It requires Al Viro's directory-in-pcache patch:

    ftp://ftp.math.psu.edu/pub/viro/ext2-dir-patch-S5.gz

To apply:

    cd mysource/linux
    zcat ext2-dir-patch-S5.gz | patch -p1
    cat dx.pcache-2.4.5 | patch -p0

To create an indexed directory:

    mount /dev/hdxxx /test -o index
    mkdir /test/foo

No known bugs, please test, thanks in advance.
