It looks like both of these can be merged eventually. The code changes in ll_rw_block for LVM and MD are similar, and it would be nice to have coherent single RAID subsystem in the kernel. Also, I'm not sure how many of you are aware of LLD work from MIT. LLD is "Logical Disk" which tries to solve problems that are usually solved by LFS or other extent based FS with journaling. The neat idea behind LLD is that rather than motifying the FS or writing a new FS to support large extent based I/O coupled with journaling, you can do this at block I/O level, under FS layer. The example software implementation is based on MINIX and a bit outdated. However, it seems reasonable to start looking into merging this into LVM framework. Of course, given the "free time" if I can manage, I would be very willing to help in the effort, since I am interested in such a thing. Finally, great work all you LVM folks! -- Hwa Jin Bae PSO Systems Inc hjb@pso.com http://www.pso.com
