I just checked your stat_sysdir output. It isn't caused by extent block 
alloc actually. So the patch doesn't work for you. Yes, the problem you 
meet is fragmentation issue, but the root cause is that inode_alloc 
can't allocate any more inodes(a little different from 1189).

I am now working on discontiguous block group. It will resolve your 
issue I think. Hope it can be get into mainline in 2.6.35.
