@Volodymyr

I did some experimenting with your test cases. My results so far are:

File System Method Performance (Typical, Minimum, Maximum) #Lost %Lost

ext3 1 0.43 0.42 0.50 1 1.00%
ext3 2 0.32 0.30 0.33 0 0.00%
ext3 3 0.19 0.16 0.20 0 0.00%
ext3 4 0.25 0.20 0.25 0 0.00%
ext3 5 0.25 0.20 0.25 0 0.00%
ext3 6 0.44 0.33 0.46 0 0.00%
ext4 1 0.45 0.44 0.50 100 100.00%
ext4 2 0.33 0.33 0.33 100 100.00%
ext4 3 0.20 0.20 0.21 0 0.00%
ext4 4 0.25 0.25 0.33 0 0.00%
ext4 5 0.25 0.25 0.26 0 0.00%
ext4 6 0.44 0.33 0.41 0 0.00%

Ext4 will zero-length all the files in Ext 4 with test cases 1 and 2. I am working on downloading a revised kernel with the patch. This is my first time doing a recompile for a jaunty release, so this may take a while.
