Agreed. I am considering the online defrag function for ext4 and thinking that your following patch set for multi-block allocation is useful to search contiguous free blocks for the defragmentation. "[RFC] extents,mballoc,delalloc for 2.6.16.8" http://marc.theaimsgroup.com/?l=linux-ext4&m=114669168616780&w=2 I will send the patch of simple defrag implementation for ext4 later.
