    ocfs2: temporarily remove extent map caching · 363041a5
    Mark Fasheh authored
    The code in extent_map.c is not prepared to deal with a subtree being
    rotated between lookups. This can happen when filling holes in sparse files.
    Instead of a lengthy patch to update the code (which would likely lose the
    benefit of caching subtree roots), we remove most of the algorithms and
    implement a simple path based lookup. A less ambitious extent caching scheme
    will be added in a later patch.
