Thanks for posting, I just have to add that this version has not been
thoroughly tested yet, so I can't promise that there are no unexpected
failures/bugs. Especially I'm not sure yet if it is suitable for really
large image, since I replaced all vmalloc() calls by __get_free_pages()
in order to save kernel vmalloc space (i.e. the "out of vmalloc memory"
error when setting preload to high numbers), primarily for testing. For
images with a block index larger than 2MB, this will for sure fail to
work!  So, please wait for an official release before using cloop 2.625
for a cloop-based distribution, or at least, please do a lot of
stress-testing before.

With kind regards
