I've added online defrag version 0.95 into the ext4 patch queue. Because of the recent patch I've added to remove the old legacy block allocator patches 7 through 11 would no longer apply, and so they are commented out in the patch queue. In some cases, the patches are ones that would go away soon anyway. In the case of EXT4_IOC_RESERVE_BLOCK ioctl, it was non-functional in the common case where mballoc was in use, since mballoc never used any of the legacy block reservation code; so any user space that depended on EXT4_IOC_RESERVE_BLOCK ioctl couldn't possibly have worked. If there are needed functions that were removed from mballoc.c that really are necessary, we can certainly look at adding them back --- but I would want to check to see if there is similar code in mballoc that we can use instead. One of my concerns is that there is been duplicated code in balloc.c, mballoc.c, extents.c, and defrag.c and one of the reasons why I wanted to pull out the legacy block allocation code was to eliminate some of the duplicated code, and to hopefully expose more of this duplicated code. In the end it should make all the ext4 code base and the defrag code more easy to understand and much more robust.
