this time linux can't perform many operations in the single directory.
following patches are intended to solve this limitation. locking is
broken into two stages: at first we protect dcache locking 'part of
directory' using hash, at second (inside ext3) we protect htree structure.
in both cases I use dynamic locks. there are several know issues to be
solved yet (say, this patches don't let several renames in single dir).
